The block cipher family for lightweight devices, KTANTAN, is analyzed in this paper. We propose a new cryptanalysis method which improves results of Meet-in-the-Middle attacks on K...
Abstract. Protecting an implementation against Side Channel Analysis for Reverse Engineering (SCARE) attacks is a great challenge and we address this challenge by presenting a fir...
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...
Abstract. Since Crypto 2004, hash functions have been the target of many attacks which showed that several well-known functions such as SHA-0 or MD5 can no longer be considered sec...
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...
