Abstract
Abstract An improvement to Serpent algorithm will be proposed . Serpent algorithm is a Feistel network , iterating a simple encryption function 32 times . The block size is 256 bits , and the key can be any length up to 256 bytes . The proposed algorithm is designed to take advantage of the powerful facility , which is supported by Serpent algorithm with overcoming its weaknesses , resulting in a much improved security / performance tradeoff over existing ciphers . As a result , the proposed algorithm offers better security than Serpent algorithm . The proposed algorithm is compact , simple and easy to understand . It increases the block size to overcome the matching cipher text and brute force attacks .
