Cryptanalysis of DES Implemented on Computers with Cache
TL;DR: The results of applying an attack against the Data Encryption Standard (DES) implemented in some applications, using side-channel information based on CPU delay as proposed in (11), found that the cipher can be broken with 2 known plaintexts and 2 24 calculations at a success rate > 90%, using a personal computer with 600-MHz Pentium III.
Book ChapterDOI
Impossible Differential Cryptanalysis of CLEFIA
TL;DR: This paper reports impossible differential cryptanalysis on the 128-bit block cipher CLEFIA that was proposed in 2007, including new 9-round impossible differentials forCLEFIA, and the result of an impossible differential attack using them.
Journal ArticleDOI
Improving cache attacks by considering cipher structure
TL;DR: This paper provided the cache attack in which the average method is embodied, and provides improved key estimation, and includes the study on the attack that exploits internal collision.
Book ChapterDOI
Higher Order Differential Attacks on Reduced-Round MISTY1
TL;DR: It is shown that higher order differential attacks can be successful against 6-round and 7-round versions of MISTY1 with FL functions, which signifies the first successful attack on7-round MISTy1 without limiting conditions such as a weak key.
