A Study on a Cache Attack for SEED
Yoshitaka Ikeda, Takenori Ichikawa, Toshinobu Kaneko (Tokyo Univ. of Science)
Abstract (in Japanese) (See Japanese page) 
(in English) In 2002, Tsunoo et al. proposed a cache attack using fluctuation of encryption times on a software implementation for CPU with cache. In general, cache attack can be applied for any ciphers which have substitution boxes.
The original cache attack uses differences between plaintext bytes for its attack equation.

In 2004, we introduced a new cache attack using differnces between the corresponding bytes of plaintexts,
which reduced computational complexity of cache attack for Camellia.
In this paper, we modified the idea to fit for the round function using arithmetic addition and applied it to SEED for which a cache attack had not been reported.
