The cipher is based on Advanced Encryption Standard (AES) operating in counter mode, used for generating keys, and a 3-round version of Serpent for encrypting actual content. The Cascaded Cipher has not been subject to an open peer review process. A license for using the Cascaded Cipher is required from Intel Corporation. Serpent - A New Block Cipher Proposal for AES Serpent was selected as one of the 5 AES finalists Serpent is a new cipher proposal for the Advanced Encryption Standard. The original version, Serpent-0, presented at Mar 23, 1998 · We propose a new block cipher as a candidate for the Advan- ced Encryption Standard. Its design is highly conservative, yet still allows a very efficient implementation. It uses the well-understood DES S-boxes in a new structure that simultaneously allows a more rapid avalanche, a more efficient bitslice implementation, and an easy analysis Cryptography - 256 bit ciphers. Hashing - 512 bit functions. Reference source code and submissions to international cryptographic designs contests. Serpent is a symmetric key block cipher which was a finalist in the Advanced Encryption Standard (AES) contest, where it came second to Rijndael. Serpent was designed by Ross Anderson, Eli Biham, and Lars Knudsen. Like other AES submissions, Serpent has a block size of 128 bits and supports a key size of 128, 192 or 256 bits. [ 2 ]

Serpent Algorithm, one of the most important proposed Algorithm for AES (Advanced encryption standard) which haven't been paid attention like Rijndael Algorithm but still it is considered as a The cipher is a Substitution-permutation network and uses two 4-bit S-boxes. The key selects which S-boxes are used. The key selects which S-boxes are used. A later Lucifer was a 16-round Feistel network , also on 128-bit blocks and 128-bit keys, described in (Sorkin, 1984). Implements the Serpent algorithm, a 128 bit block cipher with variable key length, designed R. Anderson, E. Biham, L. Knudsena. You should call Cipher.getInstance with the "Serpent" algorithm name to get a Cipher object for the Serpent cipher. You optionally may specify operation mode and padding scheme (the default operation mode used by the

Serpent is a 32-round SP-network operating on four 32-bit words, thus giving a block size of 128 bits. All values used in the cipher are represented as bit- streams. The indices of the bits are counted from 0 to bit 31 in one 32-bit word, 0 to bit 127 in 128-bit blocks, 0 to bit 255 in 256-bit keys, and so on.

Commonly known as PTW attack, it can break WEP encryption in Wi-Fi on an ordinary computer in negligible time. This is an improvement of the original Fluhrer, Mantin and Shamir attack published in 2001.
