, 2011 This chapter presents the main Side-Channel Attacks, a kind of hardware cryptanalytic techniques which exploits the physical behavior of an IC to extract secrets implied in cryptographic operations. We show in this chapter the main modern concepts about Side Channel Attacks (Simple and Differential Power Analysis) and how they can be deployed on FPGA ...

Ozone: Efficient Execution with Zero Timing Leakage for Modern Microarchitectures
, 2017 Time variation during program execution can leak sensitive information. Time variations due to program control flow and hardware resource contention have been used to steal encryption keys in cipher implementations such as AES and RSA.

Optimal Collision Side-Channel Attacks [PDF]
, 2020 Collision side-channel attacks are effective attacks against cryptographic implementations, however, optimality and efficiency of collision side-channel attacks is an open question. In this paper, we show that collision side-channel attacks can be derived using maximum likelihood principle when the distribution of the values of the leakage function is ...

DR.SGX: Hardening SGX Enclaves against Cache Attacks with Data Location Randomization
, 2019 Recent research has demonstrated that Intel's SGX is vulnerable to software-based side-channel attacks. In a common attack, the adversary monitors CPU caches to infer secret-dependent data accesses patterns. Known defenses have major limitations, as they

A Novel Side-Channel in Real-Time Schedulers
, 2019 We demonstrate the presence of a novel scheduler side-channel in preemptive, fixed-priority real-time systems (RTS); examples of such systems can be found in automotive systems, avionic systems, power plants and industrial control systems among others ...

AES Side-Channel Countermeasure using Random Tower Field Constructions [PDF]
, 2012 International audienceMasking schemes to secure AES implementations against side-channel attacks is a topic of ongoing research. The most sensitive part of the AES is the non-linear SubBytes operation, in particular, the inversion in GF(2^8), the Galois ...
