Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Automated Vulnerability Discovery in Distributed Systems

Rachid Guerraoui, George Candea, Radu Banabic

In this paper we present a technique for automatically assessing the amount of damage a small number of participant nodes can inﬂict on the overall performance of a large distributed system. We propose a feedback-driven tool that synthesizes malicious node ...

A First Step Towards Automatic Application of Power Analysis Countermeasures

Paolo Ienne, Francesco Regazzoni, Philip Brisk, Ali Galip Bayrak

In cryptography, side channel attacks, such as power analysis, attempt to uncover secret information from the physical implementation of cryptosystems rather than exploiting weaknesses in the cryptographic algorithms themselves. The design and implementati ...

Expression analysis of novel striatal-enriched genes in Huntington disease

Selective degeneration of striatal neurons is a pathologic hallmark of Huntington disease (HD). The exact mechanism(s) behind this specific neurodegeneration is still unknown. Expression studies of diseased human post-mortem brain, as well as different mou ...

Way Stealing: Cache-assisted Automatic Instruction Set Extensions

Edoardo Charbon, Paolo Ienne, Ties Jan Henderikus Kluter, Philip Brisk

This paper introduces Way Stealing, a simple architectural modification to a cache-based processor to increase data bandwidth to and from application-specific Instruction Set Extensions (ISEs). Way Stealing provides more bandwidth to the ISE-logic than the ...

Statistical sampling of microarchitecture simulation

Babak Falsafi

Current software-based micro architecture simulators are many orders of magnitude slower than the hardware they simulate. Hence, most microarchitecture design studies draw their conclusions from drastically truncated benchmark simulations that are often in ...

Exploiting reference idempotency to reduce speculative storage overflow

Babak Falsafi

Recent proposals for multithreaded architectures employ speculative execution to allow threads with unknown dependences to execute speculatively in parallel. The architectures use hardware speculative storage to buffer speculative data, track data dependen ...

A case for asymmetric-cell cache memories

Babak Falsafi

In this paper, we make the case for building high-performance asymmetric-cell caches (ACCs) that employ recently-proposed asymmetric SRAMs to reduce leakage proportionally to the number of resident zero bits. Because ACCs target memory value content (indep ...

Security Aspects of Inter-Vehicle Communications

Jean-Pierre Hubaux, Maxime Raya

Inter-Vehicular Communications (IVC) are a cornerstone of the future intelligent transportation systems. A crucial enabling component of IVC is its security and privacy. Indeed, as vehicular computing systems become interconnected, there will be new venues ...

Implicitly-multithreaded processors

Babak Falsafi

This paper proposes the Implicitly-MultiThreaded (IMT) architecture to execute compiler-specified speculative threads on to a modified Simultaneous Multithreading pipeline. IMT reduces hardware complexity by relying on the compiler to select suitable threa ...

Security flaws induced by CBC padding - Applications to SSL, IPSEC, WTLS...

Serge Vaudenay

In many standards, e.g. SSL/TLS, IPSEC, WTLS, messages are first pre-formatted, then encrypted in CBC mode with a block cipher. Decryption needs to check if the format is valid. Validity of the format is easily leaked from communication protocols in a chos ...
