Proposed A Permutation and Substitution Methods of Serpent Block Cipher

Serpent: A New Block Cipher Proposal

We propose a new block cipher as a candidate for the Advanced 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 that enables us to demonstrate its security against all ...

A Novel Block Cipher Involving a Key bunch Matrix and a Key-based Permutation and Substitution

In this paper, we have developed a novel block cipher involving a key bunch matrix supported by a key-based permutation and a key-based substitution. In this analysis, the decryption key bunch matrix is obtained by using the given encryption key bunch matrix and the concept of multiplicative inverse. From the cryptanalysis carried out in this investigation, we have seen that the strength of the...

A Dynamic FPGA Implementation of the Serpent Block Cipher

A JBits implementation of the Serpent block cipher in a Xilinx FPGA is described. JBits provides a Java-based Application Programming Interface (API) for the run-time modification of the configuration bitstream. This allows dynamic circuit specialization based on a specific key and mode (encrypt or decrypt). Subkeys are computed in software and treated as constants in the Serpent datapath. The ...

Serpent: A Flexible Block Cipher With Maximum Assurance

A Block Cipher Generation Using Color Substitution

The most powerful and common approach to countering the threats to network / information security is encryption [1]. Even though it is very powerful, the cryptanalysts are very intelligent and they were working day and night to break the ciphers. To make a stronger cipher it is recommended that to use: More stronger and complicated encryption algorithms, Keys with more number of bits (Longer ke...
