Abstract. The security of the alleged RC4 stream cipher and some variants is investigated. Cryptanalytic algorithms are developed for a known plaintext attack where only a small se...

Abstract. This paper introduces a cryptographic paradigm called selfescrowed encryption, a concept initiated by kleptography. In simple words, a self-escrowed public-key cryptosyst...
In this paper we construct a practical group blind signature scheme. Our scheme combines the already existing notions of blind signatures and group signatures. It is an extension o...
Constructions for hash functions based on a block cipher are studied where the size of the hashcode is equal to the block length of the block cipher and where the key size is appro...
This paper presents compact message formats for onion routing circuit construction using the Sphinx methodology developed for mixes. We significantly compress the circuit constru...
