Flush+Reload攻击是以Cache结构构建隐蔽信道,在加密算法执行路径上进行指令攻击,针对OpenSSL0.9.8.b中AES加密代码实现,分析了其加密实现的薄弱点在于一次加密只使用一次Te4表,提出了一种针对AES最后一轮加密实施Flush+Reload攻击的方法;实验结果表明:当收集280×103的AES加密密文和计时数据后,通过表项值与密文值的异或运算,找到最多的共有解可得到最后一...
Modern cryptography requires the ability to securely generate pseudorandom numbers. However, despite decades of work on side channel attacks, there is little discussion of their application to pseudor...

DAWG: A Defense Against Cache Timing Attacks in Speculative Execution Processors
secure processor cache timing attack cache partitioning
2018/5/11
Software side channel attacks have become a serious concern with the recent rash of attacks on speculative processor architectures. Most attacks that have been demonstrated exploit the cache tag state...
Cache-Timing Attacks on RSA Key Generation

2018/4/25
During the last decade, constant-time cryptographic software has quickly transitioned from an academic construct to a concrete security requirement for real-world libraries. Most of OpenSSL's constant...
Drive-by Key-Extraction Cache Attacks from Portable Code
Side-channel attack cache attack web page confinement
2018/2/1
We show how malicious web content can extract cryptographic secret keys from the user's computer. The attack uses portable scripting languages supported by modern browsers to induce contention for CPU...
Bounding the cache-side-channel leakage of lattice-based signature schemes using program semantics
cache side channels lattice-based signature schemes program analysis
2017/9/28
In contrast to classical signature schemes, such as RSA or ECDSA signatures, the lattice-based signature scheme ring-TESLA is expected to be resistant even against quantum adversaries. Due to a recent...
