The SC2000 block cipher has a 128-bit block size and a user key of 128, 192 or 256 bits, which employs a total of 6.5 rounds if a 128bit user key is used. It is a CRYPTREC recommen...
Square is 8-round SPN structure block cipher and its round function and key schedule have been slightly modified to design building blocks of Rijndael. Key schedule of Square is s...
Cryptographic hash functions are often built on block ciphers in order to reduce the security of the hash to that of the cipher, and to minimize the hardware size. Proven secure co...
With chosen-IV chosen texts, David Wagner has analyzed the multiple modes of operation proposed by Eli Biham in FSE’98. However, his method is too unrealistic. We use only known-...
