Software following this paradigm is often referred to as “constant-time” software and typically involves following three rules: 1) never branch on a secret-dependent condition, 2) never access memory at a secret-dependent location, and 3) avoid variable-time arithmetic operations on secret data. The third rule requires knowledge about such variable-time arithmetic instructions, or vice versa, which operations are safe to use on secret inputs. For a long time, this knowledge was based on either documentation or microbenchmarks, but critically, there were never any guarantees for future microarchitectures. This changed with the introduction of the data-operand-independent-timing (DOIT) mode on Intel CPUs and, to some extent, the data-independent-timing (DIT) mode on Arm CPUs. Both Intel and Arm document a subset of their respective instruction sets that are intended to leak no information about their inputs through timing, even on future microarchitectures if the CPU is set to run in a dedicated DOIT (or DIT) mode.In this paper, we present a principled solution that leverages DOIT to enable cryptographic software that is future-proof constant-time, in the sense that it ensures that only instructions from the DOIT subset are used to operate on secret data, even during speculative execution after a mispredicted branch or function return location. For this solution, we build on top of existing security type systems in the Jasmin framework for high-assurance cryptography.We then use our solution to evaluate the extent to which existing cryptographic software built to be “constant-time” is already secure in this stricter paradigm implied by DOIT and what the performance impact is to move from constant-time to future-proof constant-time.</jats:p>"}]},{"user_id":"125442","_id":"65538","type":"journal_article","publication":"IACR Transactions on Cryptographic Hardware and Embedded Systems","status":"public","abstract":[{"lang":"eng","text":"<jats:p>Developers implementing elliptic curve cryptography (ECC) face a wide range of implementation choices created by decades of research into elliptic curves. The literature on elliptic curves offers a plethora of curve models, scalar multipliers, and addition formulas, but this comes with the price of enabling attacks to also use the rich structure of these techniques. Navigating through this area is not an easy task and developers often obscure their choices, especially in black-box hardware implementations. Since side-channel attackers rely on the knowledge of the implementation details, reverse engineering becomes a crucial part of attacks.This work presents ECTester – a tool for testing black-box ECC implementations. Through various test suites, ECTester observes the behavior of the target implementation against known attacks but also non-standard inputs and elliptic curve parameters. We analyze popular ECC libraries and smartcards and show that some libraries and most smartcards do not check the order of the input points and improperly handle the infinity point. Based on these observations, we design new techniques for reverse engineering scalar randomization countermeasures that are able to distinguish between group scalar randomization, additive, multiplicative or Euclidean splitting. Our techniques do not require side-channel measurements; they only require the ability to set custom domain parameters, and are able to extract not only the size but also the exact value of the random mask used. Using the techniques, we successfully reverse-engineered the countermeasures on 13 cryptographic smartcards from 5 major manufacturers – all but one we tested on. Finally, we discuss what mitigations can be applied to prevent such reverse engineering, and whether it is possible at all.</jats:p>"}],"author":[{"first_name":"Vojtech","full_name":"Suchanek, Vojtech","last_name":"Suchanek"},{"first_name":"Jan","full_name":"Jancar, Jan","last_name":"Jancar"},{"first_name":"Jan","full_name":"Kvapil, Jan","last_name":"Kvapil"},{"first_name":"Petr","full_name":"Svenda, Petr","last_name":"Svenda"},{"first_name":"Łukasz","full_name":"Chmielewski, Łukasz","last_name":"Chmielewski"}],"date_created":"2026-04-30T09:31:59Z","volume":2025,"publisher":"Universitatsbibliothek der Ruhr-Universitat Bochum","date_updated":"2026-04-30T09:32:25Z","doi":"10.46586/tches.v2025.i4.290-316","title":"ECTester: Reverse-engineering side-channel countermeasures of ECC implementations","issue":"4","publication_status":"published","publication_identifier":{"issn":["2569-2925"]},"citation":{"apa":"Suchanek, V., Jancar, J., Kvapil, J., Svenda, P., &#38; Chmielewski, Ł.

Our first main result shows\r\nthat, surprisingly, QSAT on qubits can remain $\\mathsf{QMA}_1$-hard, in that\r\n$(2,5)$-QSAT is $\\mathsf{QMA}_1$-complete. In contrast, $2$-SAT on qubits is\r\nwell-known to be poly-time solvable [Bravyi, 2006]. Our second main result\r\nproves that $(3,d)$-QSAT on the 1D line with $d\\in O(1)$ is also\r\n$\\mathsf{QMA}_1$-hard. Finally, we initiate the study of 1D $(2,d)$-QSAT by\r\ngiving a frustration-free 1D Hamiltonian with a unique, entangled ground state.\r\n  Our first result uses a direct embedding, combining a novel clock\r\nconstruction with the 2D circuit-to-Hamiltonian construction of [Gosset, Nagaj,\r\n2013]. Of note is a new simplified and analytic proof for the latter (as\r\nopposed to a partially numeric proof in [GN13]). This exploits Unitary Labelled\r\nGraphs [Bausch, Cubitt, Ozols, 2017] together with a new \"Nullspace Connection\r\nLemma\", allowing us to break low energy analyses into small patches of\r\nprojectors, and to improve the soundness analysis of [GN13] from\r\n$\\Omega(1/T^6)$ to $\\Omega(1/T^2)$, for $T$ the number of gates. Our second\r\nresult goes via black-box reduction: Given an arbitrary 1D Hamiltonian $H$ on\r\n$d'$-dimensional qudits, we show how to embed it into an effective null-space\r\nof a 1D $(3,d)$-QSAT instance, for $d\\in O(1)$.

Companies try to tackle challenges regarding their differentiation and profitability using digital services. One specific type of digital services are smart services, which are digital services built on data from smart products. Introducing these kinds of offerings into the portfolio of manufacturing companies is not trivial. Moreover, they require conscious action to align all relevant capabilities to realize the respective business goals. However, what capabilities are generally relevant for smart services remains opaque. We conducted a systematic literature review to identify them and extended the results through an interview study. Our analysis results in 78 capabilities clustered among 12 principles and six dimensions. These results provide significant support for the smart service transformation of manufacturing companies and for structuring the research field of smart services."}],"user_id":"66731","department":[{"_id":"563"},{"_id":"241"}],"_id":"48632","language":[{"iso":"eng"}],"keyword":["Digital Servitization","Transformation","Capabilities","Maturity","Smart Services"]}]
