We proposed a new block cipher, Serpent, as a candidate for the Advanced Encryption Standard. This algorithm uses a new structure that simultaneously allows a more rapid avalanche,...
The need for lightweight (that is, compact, low-power, low-energy) cryptographic hash functions has been repeatedly expressed by application designers, notably for implementing RFI...
Abstract. AES is the most widely used block cipher today, and its security is one of the most important issues in cryptanalysis. After 13 years of analysis, related-key attacks wer...
In recent years, the chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques.Inthis communication,weproposea ...
A weak pseudorandom function (wPRF) is a cryptographic primitive similar to ? but weaker than ? a pseudorandom function: for wPRFs one only requires that the output is pseudorandom...
