TLDR
Wang et al. as mentioned in this paper presented an improved cache trace attack on AES and CLEFIA by considering Cache miss trace information and S-box misalignment, and obtained 128-bit AES-128 key for about 220 samples within seconds.Abstract:
This paper presents an improved Cache trace attack on AES and CLEFIA by considering Cache miss trace information and S-box misalignment. In 2006, O. Aciicmez et al. present a trace driven Cache attack on AES first two rounds, and point out that if the Cache element number of the Cache block is 16, at most 48-bit of AES key can be obtained in the first round attack. Their attack is based on the ideal case when S-box elements are perfected aligned in the Cache block. However, this paper discovers that, the S-box elements are usually misaligned, and due to this feature and by considering Cache miss trace information, about 200 samples are enough to obtain full 128-bit AES key within seconds. In 2010, Chester Rebeiro et al. present the first trace driven Cache attack on C LEFIA by considering Cache hit information and obtain 128bit key with 2 CLEFIA encryptions. In this paper, we present a new attack on CLEFIA by considering Cache miss information and S-box misalignment features, finally successfully obtain CLEFIA-128 key for about 220 samples within seconds.read more

Cache Games -- Bringing Access-Based Cache Attacks on AES to Practice
TL;DR: This paper considers the AES block cipher and presents an attack which is capable of recovering the full secret key in almost real time for AES-128, requiring only a very limited number of observed encryptions, and is the first working attack on AES implementations using compressed tables.

Cache-Access pattern attack on disaligned AES t-tables
Raphael Spreitzer,Thomas Plos +1 more
TL;DR: An access-driven cache attack, which is based on the analysis of memory-access patterns due to the T-table accesses of the Advanced Encryption Standard (AES), is demonstrated and an enhancement is presented, which in some cases allows to recover the secret key without a subsequent brute-force key search.
