Software cache-based side channel attacks present serious threats to modern computer systems. Using caches as a side channel, these attacks are able to derive secret keys used in ...
Rijndael is the new Advanced Encryption Standard designed by V. Rijmen and J. Daemen and chosen as AES by the NIST in October 2000. Surprisingly, the number of cryptanalyses agains...
Abstract. Recently, Shen et al. proposed an improvement on YangShieh’s timestamp-based password authentication scheme using smart cards. Then they claimed that their scheme canno...
The DES has reached the end of its lifetime due to its too short key length and block length (56 and 64 bits respectively). As we are awaiting the new AES, triple (and double) encr...
In 1980 Hellman introduced a general technique for breaking arbitrary block ciphers with N possible keys in time T and memory M related by the tradeoff curve TM2 = N2 for 1 T N. ...
