The taskof the system is to serve any collection of lookup requests with at most oneper non-blocked server in an efficient way despite this attack.

At the same time, our approach guarantees that software licenses are bound to users and that their validity is checked before execution. Thus, DRM constitutes an incentive for software providers to take part in such a future cloud computing scenario.

Instead the contents decay rather slowly, in particular if the DRAM chips are cooled to low temperatures. This effect opens an attack vector on cryptographic applications that keep decrypted keys in DRAM. An attacker with access to the target computer can reboot it or remove the RAM modules and quickly copy the RAM contents to non-volatile memory. By exploiting the known cryptographic structure of the cipher and layout of the key data in memory, in our application an AES key schedule with redundancy, the resulting memory image can be searched for sections that could correspond to decayed cryptographic keys; then, the attacker can attempt to reconstruct the original key. However, the runtime of these algorithms grows rapidly with increasing memory image size, error rate and complexity of the bit error model, which limits the practicability of the approach.In this work, we study how the algorithm for key search can be accelerated with custom computing machines.

Research in distributed systems is now at a crucialpoint in its evolution, marked by the importance of dynamic systems such as peer-to-peer networks, large-scale wireless sensor networks, mobile ad hoc networks, cloud computing, robotic networks, etc. Moreover, new applications such as grid and web services, banking and e-commerce, e-health and robotics, aerospace and avionics, automotive, industrial process control, etc. have joined the traditional applications of distributed systems. The theory of self-stabilization has been enriched in the last 30 years by high quality research contributions in the areas of algorithmic techniques, formal methodologies, model theoretic issues, and composition techniques. All these areas are essential to the understanding and maintenance of self-properties in fault-tolerant distributed systems.","lang":"eng"}],"editor":[{"full_name":"Richa, Andrea W.","last_name":"Richa","first_name":"Andrea W."},{"first_name":"Christian","last_name":"Scheideler","full_name":"Scheideler, Christian","id":"20792"}],"file":[{"file_size":169564,"file_id":"1569","file_name":"577-SSS2012Richa-Scheideler.pdf","access_level":"closed","date_updated":"2018-03-21T13:09:19Z","creator":"florida","date_created":"2018-03-21T13:09:19Z","success":1,"relation":"main_file","content_type":"application/pdf"}],"status":"public","project":[{"name":"SFB 901","_id":"1"},{"_id":"13","name":"SFB 901 - Subprojekt C1"},{"_id":"4","name":"SFB 901 - Project Area C"}],"_id":"577","user_id":"15504","department":[{"_id":"79"}],"ddc":["040"],"file_date_updated":"2018-03-21T13:09:19Z","has_accepted_license":"1","year":"2012","citation":{"bibtex":"@book{Richa_Scheideler_2012, title={Stabilization, Safety, and Security of Distributed Systems}, DOI={<a href=\"https://doi.org/10.1007/978-3-642-33536-5\">10.1007/978-3-642-33536-5</a>}, year={2012} }","mla":"Richa, Andrea W., and Christian Scheideler, editors. <i>Stabilization, Safety, and Security of Distributed Systems</i>. 2012, doi:<a href=\"https://doi.org/10.1007/978-3-642-33536-5\">10.1007/978-3-642-33536-5</a>.","short":"A.W.

In this work we introduce a distributed local algorithm for arranging a set of nanoparticles on the discrete plane into specic geometric shapes, for instance a rectangle. The concept of a particle we use can be seen as a simple mobile robot with the following restrictions: it can only view the state of robots it is physically connected to, is anonymous, has only a constant size memory, can only move by using other particles as an anchor point on which it pulls itself alongside, and it operates in Look-Compute-Move cycles. The main result of this work is the presentation of a random distributed local algorithm which transforms any given connected set of particles into a particular geometric shape. As an example we provide a version of this algorithm for forming a rectangle with an arbitrary predened aspect ratio. To the best of our knowledge this is the rst work that considers arrangement problems for these types of robots."}],"status":"public","file":[{"creator":"florida","date_created":"2018-03-15T08:39:33Z","date_updated":"2018-03-15T08:39:33Z","file_name":"581-IPDPS2012-Scheideler_Huellmann.pdf","access_level":"closed","file_id":"1263","file_size":373131,"content_type":"application/pdf","relation":"main_file","success":1}],"_id":"581","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt C1","_id":"13"},{"_id":"4","name":"SFB 901 - Project Area C"}],"department":[{"_id":"79"},{"_id":"63"}],"user_id":"14955","ddc":["040"],"language":[{"iso":"eng"}],"file_date_updated":"2018-03-15T08:39:33Z"},{"citation":{"apa":"Petrlic, R.
