Cryptanalysis of the Vesta-2M Stream Cipher

Marina Pudovkina

Abstract: In this paper the security of the stream cipher Vesta-2M is investigated. Cryptanalytic algorithm is developed for a known plaintext attack where only a small segment of plaintext is assumed to be known. The complexity the attack is estimated the time of searching through the square root of all possible initial states.
