The AES block cipher has a 128-bit block length and a user key of 128, 192 or 256 bits, released by NIST for data encryption in the USA; it became an ISO international standard in ...
We compare the five candidates for the Advanced Encryption Standard based on their performance on the Alpha 21264, a 64-bit superscalar processor. There are several new features o...
This paper describes a new public-key cryptosystem where the ciphertext is obtained by multiplying the public-keys indexed by the message bits and the cleartext is recovered by fac...
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...
Bit vectors and bit operations are proposed for efficient propositional inference. Bit arithmetic has efficient software and hardware implementations, which can be put to advantage...
