The basic idea of AC is to sacrifice high precision for low energy by allowing hardware to carry out “approximately correct” calculations. This provides a major challenge for software quality assurance: programs successfully verified to be correct might be erroneous on approximate hardware. In this letter, we present a novel approach for determining under what conditions a software verification result is valid for approximate hardware. To this end, we compute the allowed tolerances for AC hardware from successful verification runs. More precisely, we derive a set of constraints which—when met by the AC hardware—guarantees the verification result to carry over to AC. On the practical side, we furthermore: 1) show how to extract tolerances from verification runs employing predicate abstraction as verification technology and 2) show how to check such constraints on hardware designs. We have implemented all techniques, and exemplify them on example C programs and a number of recently proposed approximate adders.","lang":"eng"}],"status":"public","has_accepted_license":"1","date_created":"2017-12-11T16:11:00Z","file":[{"content_type":"application/pdf","date_updated":"2018-11-02T15:27:04Z","success":1,"relation":"main_file","file_size":523362,"file_id":"5303","creator":"ups","access_level":"closed","date_created":"2018-11-02T15:27:04Z","file_name":"08053741.pdf"}],"publisher":"Institute of Electrical and Electronics Engineers (IEEE)","author":[{"last_name":"Isenberg","full_name":"Isenberg, Tobias","first_name":"Tobias"},{"last_name":"Jakobs","full_name":"Jakobs, Marie-Christine","first_name":"Marie-Christine"},{"last_name":"Pauck","id":"22398","first_name":"Felix","full_name":"Pauck, Felix"},{"id":"573","last_name":"Wehrheim","full_name":"Wehrheim, Heike","first_name":"Heike"}],"file_date_updated":"2018-11-02T15:27:04Z","publication":"IEEE Embedded Systems Letters","doi":"10.1109/LES.2017.2758200","date_updated":"2022-01-06T06:50:39Z","language":[{"iso":"eng"}],"title":"Validity of Software Verification Results on Approximate Hardware","project":[{"name":"SFB 901","_id":"1"},{"_id":"3","name":"SFB 901 - Project Area B"},{"_id":"12","name":"SFB 901 - Subproject B4"}],"publication_identifier":{"issn":["1943-0663","1943-0671"]},"publication_status":"published","department":[{"_id":"77"}]},{"publication":"Proceedings of the 40th International Conference on Software Engineering (ICSE)","file_date_updated":"2018-11-21T10:50:51Z","publisher":"ACM","author":[{"last_name":"Beyer","full_name":"Beyer, Dirk","first_name":"Dirk"},{"last_name":"Jakobs","first_name":"Marie-Christine","full_name":"Jakobs, Marie-Christine"},{"full_name":"Lemberger, Thomas","first_name":"Thomas","last_name":"Lemberger"},{"first_name":"Heike","full_name":"Wehrheim, Heike","last_name":"Wehrheim","id":"573"}],"file":[{"access_level":"closed","date_created":"2018-11-21T10:50:51Z","file_name":"Reducer-Based Construction of Conditional Verifiers.pdf","content_type":"application/pdf","date_updated":"2018-11-21T10:50:51Z","relation":"main_file","success":1,"file_size":826719,"file_id":"5783","creator":"florida"}],"date_created":"2018-01-08T10:52:51Z","has_accepted_license":"1","status":"public","abstract":[{"lang":"eng","text":"to appear"}],"ddc":["000"],"user_id":"29719","page":"1182--1193","citation":{"mla":"Beyer, Dirk, et al. “Reducer-Based Construction of Conditional Verifiers.” Proceedings of the 40th International Conference on Software Engineering (ICSE), ACM, 2018, pp. 1182--1193.","bibtex":"@inproceedings{Beyer_Jakobs_Lemberger_Wehrheim_2018, title={Reducer-Based Construction of Conditional Verifiers}, booktitle={Proceedings of the 40th International Conference on Software Engineering (ICSE)}, publisher={ACM}, author={Beyer, Dirk and Jakobs, Marie-Christine and Lemberger, Thomas and Wehrheim, Heike}, year={2018}, pages={1182--1193} }","ama":"Beyer D, Jakobs M-C, Lemberger T, Wehrheim H.

As witnesses in all theses scenarios need to be stored and processed, witnesses are required to be as small as possible. However, software verification tools – the prime suppliers of witnesses – do not necessarily construct small witnesses. In this paper, we present a formal account of proof witnesses. We introduce the concept of weakenings, reducing the complexity of proof witnesses while preserving the ability of witnessing safety.

In contrast, companies are interested in reducing the construction effort (and usually as a consequence thereof, the quality) to gain profit. The described setting is widely known as opposed preferences in quality of the product and also applies to the context of service-oriented computing. In general, service-oriented computing emphasizes the construction of large software systems out of existing services, where services are small and self-contained pieces of software that adhere to a specified interface. Several implementations of the same interface are considered as several instances of the same service. Thereby, customers are interested in buying the best service implementation for their service composition wrt. to metrics, such as costs, energy, memory consumption, or execution time. One way to ensure the service quality is to employ certificates, which can come in different kinds: Technical certificates proving correctness can be automatically constructed by the service provider and again be automatically checked by the user. Digital certificates allow proof of the integrity of a product. Other certificates might be rolled out if service providers follow a good software construction principle, which is checked in annual audits. Whereas all of these certificates are handled differently in service markets, what they have in common is that they influence the buying decisions of customers. In this paper, we review state-of-the-art developments in certification with respect to service-oriented computing.

For this task, we introduce an incremental workflow that is based on our algorithm IC3 with Zones. It proceeds in a cycle in which single models of the system are verified, and the verification results are employed for the reasoning about the entire system. Starting with the smallest instances, the verification of the safety property is carried out fast and efficient. On successful verification, the algorithm produces an inductive strengthening of the safety property. We reuse this result and try to reason about the entire parameterized timed system. To this end, we extrapolate the inductive strengthening into a candidate for the next-larger model. In case this candidate is a valid inductive strengthening for the next larger model, our main theorem reasons about all models of the parameterized timed system, stating that the safety property holds true for all models. Otherwise, the main cycle starts over with the verification of the next larger model. This workflow is iterated indefinitely, until able to reason about the entire parameterized timed system, until a counterexample trace is found, or until the single models become too large to be handled in the verification. We reuse the intermediate results in a Feedback-loop in order to accelerate the verification runs for the single models. Furthermore, we consider an extended formalism in comparison to our previous publications.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1145/2984640","date_updated":"2022-01-06T07:04:06Z","project":[{"_id":"1","name":"SFB 901"},{"_id":"12","name":"SFB 901 - Subprojekt B4"},{"_id":"3","name":"SFB 901 - Project Area B"}],"department":[{"_id":"77"}],"title":"Incremental Inductive Verification of Parameterized Timed Systems"},{"ddc":["000"],"user_id":"477","abstract":[{"lang":"eng","text":"Information Flow Analysis (IFA) aims at detecting illegal flows of information between program entities. “Legality” is therein specified in terms of various security policies.

The producer of a hardware module spends huge effort when creating a proof for a safety policy. The proof is then transferred as a certificate together with the configuration bitstream to the consumer of the hardware module, who can quickly verify the given proof. Previous work utilized SAT solvers and resolution traces to set up a PCH technology and corresponding tool flows. In this article, we present a novel technology for PCH based on inductive invariants. For sequential circuits, our approach is fundamentally stronger than the previous SAT-based one since we avoid the limitations of bounded unrolling. We contrast our technology to existing ones and show that it fits into previously proposed tool flows. We conduct experiments with four categories of benchmark circuits and report consumer and producer runtime and peak memory consumption, as well as the size of the certificates and the distribution of the workload between producer and consumer. Experiments clearly show that our new induction-based technology is superior for sequential circuits, whereas the previous SAT-based technology is the better choice for combinational circuits."}],"date_created":"2017-10-17T12:41:04Z","status":"public","has_accepted_license":"1","file":[{"access_level":"closed","file_name":"a61-isenberg.pdf","date_created":"2018-11-02T16:08:17Z","date_updated":"2018-11-02T16:08:17Z","content_type":"application/pdf","relation":"main_file","success":1,"file_size":806356,"file_id":"5324","creator":"ups"}],"file_date_updated":"2018-11-02T16:08:17Z","publication":"ACM Transactions on Design Automation of Electronic Systems","publisher":"ACM","author":[{"first_name":"Tobias","full_name":"Isenberg, Tobias","last_name":"Isenberg"},{"full_name":"Platzner, Marco","first_name":"Marco","id":"398","last_name":"Platzner"},{"first_name":"Heike","full_name":"Wehrheim, Heike","last_name":"Wehrheim","id":"573"},{"id":"3118","last_name":"Wiersema","full_name":"Wiersema, Tobias","first_name":"Tobias"}]},{"date_updated":"2022-01-06T07:03:22Z","_id":"685","doi":"10.17619/UNIPB/1-104","supervisor":[{"full_name":"Wehrheim, Heike","first_name":"Heike","id":"573","last_name":"Wehrheim"}],"type":"dissertation","citation":{"chicago":"Jakobs, Marie-Christine.

This poses, more than ever, the challenge of ensuring safety of software in the face of (1) unknown or untrusted software providers together with (2) resource-limited software consumers. The concept of Proof-Carrying Code (PCC), years ago suggested by Necula, provides one framework for securing the execution of untrusted code. PCC techniques attach safety proofs, constructed by software producers, to code. Based on the assumption that checking proofs is usually much simpler than constructing proofs, software consumers should thus be able to quickly check the safety of software. However, PCC techniques often suffer from the size of certificates (i.e., the attached proofs), making PCC techniques inefficient in practice.In this article, we introduce a new framework for the safe execution of untrusted code called Programs from Proofs (PfP). The basic assumption underlying the PfP technique is the fact that the structure of programs significantly influences the complexity of checking a specific safety property. Instead of attaching proofs to program code, the PfP technique transforms the program into an efficiently checkable form, thus guaranteeing quick safety checks for software consumers. For this transformation, the technique also uses a producer-side automatic proof of safety. More specifically, safety proving for the software producer proceeds via the construction of an abstract reachability graph (ARG) unfolding the control-flow automaton (CFA) up to the degree necessary for simple checking. To this end, we combine different sorts of software analysis: expensive analyses incrementally determining the degree of unfolding, and cheap analyses responsible for safety checking. Out of the abstract reachability graph we generate the new program. In its CFA structure, it is isomorphic to the graph and hence another, this time consumer-side, cheap analysis can quickly determine its safety.Like PCC, Programs from Proofs is a general framework instantiable with different sorts of (expensive and cheap) analysis. Here, we present the general framework and exemplify it by some concrete examples. We have implemented different instantiations on top of the configurable program analysis tool CPAchecker and report on experiments, in particular on comparisons with PCC techniques."}]},{"supervisor":[{"last_name":"Wehrheim","id":"573","first_name":"Heike","full_name":"Wehrheim, Heike"}],"language":[{"iso":"eng"}],"citation":{"chicago":"Pauck, Felix.

Moreover, quality assurance is complicated by service providers only giving information on their services in terms of domain specific concepts with only limited semantic meaning.In this paper, we propose a method for constructing service compositions based on pre-verified templates. Templates, given as workflow descriptions, are typed over a (domain-independent) template ontology defining concepts and predicates. Their meaning is defined by an abstract semantics, leaving the specific meaning of ontology concepts open, however, only up to given ontology rules. Templates are proven correct using a Hoare-style proof calculus, extended by a specific rule for service calls. Construction of service compositions amounts to instantiation of templates with domain-specific services. Correctness of an instantiation can then simply be checked by verifying that the domain ontology (a) adheres to the rules of the template ontology, and (b) fulfills the constraints of the employed template.","lang":"eng"}],"ddc":["040"],"user_id":"477","publisher":"Elsevier","author":[{"last_name":"Walther","first_name":"Sven","full_name":"Walther, Sven"},{"full_name":"Wehrheim, Heike","first_name":"Heike","id":"573","last_name":"Wehrheim"}],"publication":"Science of Computer Programming","file_date_updated":"2018-03-21T12:38:40Z","file":[{"creator":"florida","file_id":"1536","file_size":630739,"relation":"main_file","success":1,"content_type":"application/pdf","date_updated":"2018-03-21T12:38:40Z","date_created":"2018-03-21T12:38:40Z","file_name":"175-1-s2.0-S0167642316300028-main.pdf","access_level":"closed"}],"status":"public","has_accepted_license":"1","date_created":"2017-10-17T12:41:26Z","date_updated":"2022-01-06T06:53:13Z","doi":"10.1016/j.scico.2016.04.002","language":[{"iso":"eng"}],"title":"On-The-Fly Construction of Provably Correct Service Compositions - Templates and Proofs","department":[{"_id":"77"}],"project":[{"name":"SFB 901","_id":"1"},{"_id":"11","name":"SFB 901 - Subprojekt B3"},{"_id":"3","name":"SFB 901 - Project Area B"}]},{"department":[{"_id":"77"}],"project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt B4","_id":"12"},{"_id":"3","name":"SFB 901 - Project Area B"}],"editor":[{"last_name":"Jens Knoop","full_name":"Jens Knoop, Uwe Zdun","first_name":"Uwe Zdun"}],"title":"Just test what you cannot verify!","series_title":"Lecture Notes in Informatics","language":[{"iso":"eng"}],"date_updated":"2022-01-06T06:53:43Z","file":[{"access_level":"closed","file_name":"186-SEsubmission8.pdf","date_created":"2018-03-21T12:32:11Z","content_type":"application/pdf","date_updated":"2018-03-21T12:32:11Z","success":1,"relation":"main_file","file_size":55775,"file_id":"1532","creator":"florida"}],"file_date_updated":"2018-03-21T12:32:11Z","publication":"Software Engineering 2016","author":[{"last_name":"Czech","first_name":"Mike","full_name":"Czech, Mike"},{"full_name":"Jakobs, Marie-Christine","first_name":"Marie-Christine","last_name":"Jakobs"},{"id":"573","last_name":"Wehrheim","full_name":"Wehrheim, Heike","first_name":"Heike"}],"date_created":"2017-10-17T12:41:28Z","has_accepted_license":"1","status":"public","abstract":[{"text":"Software verification is an established method to ensure software safety. Nevertheless, verification still often fails, either because it consumes too much resources, e.g., time or memory, or the technique is not mature enough to verify the property.

Our techniques use this summary to construct a residual program which only contains program paths with unproven assertions. Afterwards, the residual program can be used with standard testing tools.Our first experiments show that testing profits from the partial verification.The test effort is reduced and combined verification and testing is faster than a complete verification.","lang":"eng"}],"user_id":"477","ddc":["040"],"page":"17-18","type":"conference","year":"2016","citation":{"chicago":"Czech, Mike, Marie-Christine Jakobs, and Heike Wehrheim. “Just Test What You Cannot Verify!” In Software Engineering 2016, edited by Uwe Zdun Jens Knoop, 17–18.

In a model-based software design, this interface constitutes our sole knowledge of the service at design time, while service implementations are not available. Therefore, correctness checks or detection of potential errors in service compositions has to be carried out without the possibility of executing services.

Thus, automated approaches to these tasks have been intensively studied for standard software systems. For model-based software systems, the situation is different. While error detection is still well-studied, error localization and correction is a less-studied domain. In this paper, we examine error localization and correction for models of service compositions. Based on formal definitions of error and correction in this context, we show that the classical approach of error localization and correction, i.e. first determining a set of suspicious statements and then proposing changes to these statements, is ineffective in our context. In fact, it lessens the chance to succeed in finding a correction at all.In this paper, we introduce correction proposal as a novel approach on error correction in service compositions integrating error localization and correction in one combined step. In addition, we provide an algorithm to compute such correction proposals automatically.","lang":"eng"}],"ddc":["040"],"user_id":"477","author":[{"last_name":"Krämer","full_name":"Krämer, Julia","first_name":"Julia"},{"id":"573","last_name":"Wehrheim","full_name":"Wehrheim, Heike","first_name":"Heike"}],"publication":"Proceedings of the 1st International Workshop on Formal to Practical Software Verification and Composition (VeryComp 2016)","file_date_updated":"2018-03-21T10:34:08Z","file":[{"access_level":"closed","file_name":"226-chp_3A10.1007_2F978-3-319-50230-4_35.pdf","date_created":"2018-03-21T10:34:08Z","success":1,"relation":"main_file","content_type":"application/pdf","date_updated":"2018-03-21T10:34:08Z","creator":"florida","file_id":"1507","file_size":492018}],"has_accepted_license":"1","status":"public","date_created":"2017-10-17T12:41:36Z","_id":"226","year":"2016","citation":{"short":"J.

To accelerate this validation, in the proof carrying code (PCC) paradigm the provider delivers the software together with a certificate, a formal proof of the software’s correctness. Thus, the user only checks if the attached certificate shows correctness of the delivered software.Recently, we introduced configurable program certification, a generic, PCC based framework supporting various software analyses and safety properties. Evaluation of our framework revealed that validation suffers from certificate reading. In this paper, we present two orthogonal approaches which improve certificate validation, both reducing the impact of certificate reading. The first approach reduces the certificate size, storing information only if it cannot easily be recomputed. The second approach partitions the certificate into independently checkable parts. The trick is to read parts of the certificate while already checking read parts. Our experiments show that validation highly benefits from our improvements.","lang":"eng"}],"ddc":["040"],"user_id":"477"},{"_id":"283","type":"conference","citation":{"short":"M. Czech, M.-C.

However, the resources (time and/or memory) for an exhaustive verification are not always available, and analysis then has to resort to other techniques, like testing. Most often, the already achieved partial verification results arediscarded in this case, and testing has to start from scratch.In this paper, we propose a method for combining verification and testing in which testing only needs to check the residual fraction of an uncompleted verification. To this end, the partial results of a verification run are used to construct a residual program (and residual assertions to be checked on it). The residual program can afterwards be fed into standardtesting tools. The proposed technique is sound modulo the soundness of the testing procedure. Experimental results show that this combinedusage of verification and testing can significantly reduce the effort for the subsequent testing.","lang":"eng"}],"has_accepted_license":"1","status":"public","date_created":"2017-10-17T12:41:47Z","file":[{"success":1,"relation":"main_file","date_updated":"2018-03-21T09:25:36Z","content_type":"application/pdf","creator":"florida","file_id":"1469","file_size":391253,"access_level":"closed","file_name":"283-FASEsubmission38_01.pdf","date_created":"2018-03-21T09:25:36Z"}],"author":[{"first_name":"Mike","full_name":"Czech, Mike","last_name":"Czech"},{"last_name":"Jakobs","first_name":"Marie-Christine","full_name":"Jakobs, Marie-Christine"},{"full_name":"Wehrheim, Heike","first_name":"Heike","id":"573","last_name":"Wehrheim"}],"file_date_updated":"2018-03-21T09:25:36Z","publication":"Fundamental Approaches to Software Engineering","doi":"10.1007/978-3-662-46675-9_7","date_updated":"2022-01-06T06:58:00Z","language":[{"iso":"eng"}],"series_title":"Lecture Notes in Computer Science","title":"Just test what you cannot verify!","project":[{"name":"SFB 901","_id":"1"},{"_id":"12","name":"SFB 901 - Subprojekt B4"},{"_id":"3","name":"SFB 901 - Project Area B"}],"editor":[{"last_name":"Egyed","full_name":"Egyed, Alexander","first_name":"Alexander"},{"full_name":"Schaefer, Ina","first_name":"Ina","last_name":"Schaefer"}],"department":[{"_id":"77"}]},{"department":[{"_id":"77"}],"project":[{"_id":"1","name":"SFB 901"},{"_id":"12","name":"SFB 901 - Subprojekt B4"},{"name":"SFB 901 - Project Area B","_id":"3"}],"title":"Incremental Inductive Verification of Parameterized Timed Systems","language":[{"iso":"eng"}],"date_updated":"2022-01-06T06:58:07Z","doi":"10.1109/ACSD.2015.13","publication":"Proceedings of the 15th International Conference on Application of Concurrency to System Design (ACSD)","file_date_updated":"2018-03-21T09:23:45Z","author":[{"last_name":"Isenberg","first_name":"Tobias","full_name":"Isenberg, Tobias"}],"file":[{"file_name":"285-07352419.pdf","date_created":"2018-03-21T09:23:45Z","access_level":"closed","file_size":479808,"file_id":"1466","creator":"florida","date_updated":"2018-03-21T09:23:45Z","content_type":"application/pdf","success":1,"relation":"main_file"}],"date_created":"2017-10-17T12:41:47Z","status":"public","has_accepted_license":"1","abstract":[{"text":"We propose an incremental workflow for the verification of parameterized systems modeled as symmetric networks of timed automata.

The technique ensures that the new and given program are behaviorally equivalent and that the new program is easily verifiable, thus serving as an alternative to proof-carrying code concepts. So far, this generic method has one instantiation that verifies type-state properties of programs. In this paper, we present a whole range of new instantiations, all based on data ow analyses. More precisely, we show how an imprecise but fast data ow analysis can be enhanced with a predicate analysis as to yield a precise but expensive analysis. Out of the safety proofs of this analysis, we generate new programs, again behaviorally equivalent to the given ones, which are easily verifiable\" in the sense that now the data ow analysis alone can yield precise results. An experimental evaluation practically supports our claim of easy verification.","lang":"eng"}],"ddc":["040"],"user_id":"477","series_title":"SAC '15","language":[{"iso":"eng"}],"date_updated":"2022-01-06T06:57:18Z","doi":"10.1145/2695664.2695690","department":[{"_id":"77"}],"project":[{"_id":"1","name":"SFB 901"},{"_id":"12","name":"SFB 901 - Subprojekt B4"},{"_id":"3","name":"SFB 901 - Project Area B"}],"title":"Programs from Proofs of Predicated Dataflow Analyses"},{"ddc":["040"],"user_id":"477","abstract":[{"lang":"eng","text":"Model transformation is a key concept in model-driven software engineering. The definition of model transformations is usually based on meta-models describing the abstract syntax of languages. While meta-models are thereby able to abstract from uperfluous details of concrete syntax, they often loose structural information inherent in languages, like information on model elements always occurring together in particular shapes. As a consequence, model transformations cannot naturally re-use language structures, thus leading to unnecessary complexity in their development as well as in quality assurance.In this paper, we propose a new approach to model transformation development which allows to simplify the developed transformations and improve their quality via the exploitation of the languages׳ structures. The approach is based on context-free graph grammars and transformations defined by pairing productions of source and target grammars. We show that such transformations have important properties: they terminate and are sound, complete, and deterministic."}],"date_created":"2017-10-17T12:41:48Z","status":"public","has_accepted_license":"1","publication":"Computer Languages, Systems & Structures","file_date_updated":"2018-03-21T09:22:03Z","publisher":"Elsevier","author":[{"last_name":"Besova","first_name":"Galina","full_name":"Besova, Galina"},{"last_name":"Steenken","first_name":"Dominik","full_name":"Steenken, Dominik"},{"first_name":"Heike","full_name":"Wehrheim, Heike","last_name":"Wehrheim","id":"573"}],"file":[{"relation":"main_file","success":1,"content_type":"application/pdf","date_updated":"2018-03-21T09:22:03Z","creator":"florida","file_id":"1464","file_size":1329478,"access_level":"closed","date_created":"2018-03-21T09:22:03Z","file_name":"290-BSW15-main.pdf"}],"_id":"290","page":"116-138","year":"2015","type":"journal_article","citation":{"ama":"Besova G, Steenken D, Wehrheim H.

Moreover, quality assurance is complicated by service providers only giving information on their services in terms of domain specific concepts with only limited semantic meaning. In this paper, we propose a method to construct service compositions based on pre-verifiedtemplates. Templates, given as workflow descriptions, are typed over a (domain-independent) template ontology defining concepts and predicates. Templates are proven correct using an abstract semantics, leaving the specific meaning of ontology concepts open, however, only up to given ontology rules. Construction of service compositions amounts to instantiation of templates with domain-specific services.Correctness of an instantiation can then simply be checked by verifying that the domain ontology(a) adheres to the rules of the template ontology, and (b) fulfills the constraints of the employed template."}],"citation":{"ieee":"S.

Depending on the type of safety property, proofs can however become quite large and their validation - though faster than their construction - still time consuming. In this paper we introduce a new concept for safe execution of untrusted code. It keeps the idea of putting the time consuming part of proving on the side of the code producer, however, attaches no proofs to code anymore but instead uses the proof to transform the program into an equivalent but more efficiently verifiable program. Code consumers thus still do proving themselves, however, on a computationally inexpensive level only. Experimental results show that the proof effort can be reduced by several orders of magnitude, both with respect to time and space.","lang":"eng"}],"ddc":["040"],"user_id":"477","main_file_link":[{"url":"http://eprints.uni-kiel.de/23752/"}],"citation":{"ieee":"D.
