Abstract. Helix is a high-speed stream cipher with a built-in MAC functionality. On a Pentium II CPU it is about twice as fast as Rijndael or Twofish, and comparable in speed to R...

Impossible boomerang attack [5] (IBA) is a new variant of differential cryptanalysis against block ciphers. Evident from its name, it combines the ideas of both impossible differ...
In this paper, we examine the digital hardware design and implementation of a novel compact block cipher, referred to as PUFFIN, that is suitable for embedded applications. An imp...
Large classes of weak keys have been found for the block cipher algorithm IDEA, previously known as IPES [2]. IDEA has a 128bit key and encrypts blocks of 64 bits. For a class of 2...
Abstract. SQUARE, an 8-round substitution-permutation block cipher, is considered as the predecessor of the AES. In this paper, inspired from the recent biclique attack on the AES ...
