A Survey on Various Cryptographic Algorithms for Security Enhancement

Abstract

with rapid growth of internet access users it is much easier to change the original information. Therefore many internet users worry about their document security. There is need to develop system which can protect data from hackers. Cryptography plays important role in the field of internet security. Now a day’s many encryption algorithms are available . Such as DES, Blowfish, AES and MARS etc. Each one has their own benefit. User need to choose encryption algorithm according to their need. Every algorithm has their own strength and weakness. This paper present analysis of above algorithms with various parameters such as time required for encryption and decryption, encryption key size, power consumption, and most important security provided by algorithm.
