Network-on-chip (NoC) is a critical shared resource in scalable multicore processors; however, it is well-known that shared resources can lead to side-channel attacks. In this work, we demonstrate how contention for on-chip bandwidth in GPUs can lead to fine-grain information leakage and ena...
旁路攻击(侧信道攻击、边信道攻击, Side Channel Attack, SCA) 是基于观察的被动攻击,工作流程是:采集信号 -> 统计分析 -> 报告生成 支持旁路攻击分析方法:CPA, DPA, MIA, DEMA, SEMA, SPA, CEMA, 2nd & High Order Attacks, Timing Attacks, Template Attacks, Stochastic Attacks等 支持主流密码算法:AES, ...
Side channel attacks are, probably, the one of the most challenging threats to address. For example, due to the shared cloud infrastructure, timing channels can be exited at any point in time and malicious users co-located on the same infrastructure can potentially steal sensitive data from othe...
A number of attacks can be performed against smart cards. Side-channel is a class of attacks that doesn’t try to compromise a flaw or weakness. Which of the following is not a side-channel attack? A. Differential power analysis B. Microprobing analysis C. Timing analysis D. ...
This can allow an attacker who can execute user-privileged code the ability to use this side channel to determine private keys used in cryptographic functions. It can also (theoretically) be used to perform other timing attacks against systems, such as against kernel threads running on co-residen...
The hardware systems have experienced a plethora of side-channel attacks (SCAs) in recent years with cache-based SCAs being one of the dominant threats. The SCAs exploit the architectural caveats, which invariably leak essential information during an application's execution. Shutting down the side-...
Timing-based side-channels play an important role in exposing the state of a process execution on underlying hardware by revealing information about timing and access patterns. Side-channel attacks (SCAs) are powerful cryptanalysis techniques that focus on the underlying implementation of cryptographic ci...
