A chosen-plaintext attack on two-key triple encryption noted by Merkle and Hellman is extended to a known-plaintext attack. The known-plaintext attack has lower memory requirements...
Abstract. Biham and Kocher demonstrated that the PKZIP stream cipher was weak and presented an attack requiring thirteen bytes of plaintext. The deflate algorithm “zippers” no...
The DES has reached the end of its lifetime due to its too short key length and block length (56 and 64 bits respectively). As we are awaiting the new AES, triple (and double) encr...
Serpent is a 32-round AES block cipher finalist. In this paper we present several attacks on reduced-round variants of Serpent that require less work than exhaustive search. We at...
In spite of growing importance of AES, the Data Encryption Standard is by no means obsolete. DES has never been broken from the practical point of view. The triple DES is believed ...
