Abstract
In this fast developing world, the interchange of information is playing a key role. Everything needs information and processes them. This interchange of information needs an authentication, confidentiality and integrity. The security of information is provided many algorithms. There are vast numbers of algorithms for symmetry key cipher. All these algorithms have used either complicated keys to encrypt the plain text to cipher text or a complicated algorithms used for it. The level of security of algorithms is dependent on either number of iterations or length of keys. A comparative study have been made with RSA, DES, IDEA, BAM and other algorithms with frequency distribution, bit ratio to check the security level of proposed algorithm. Finally, a comparison has been made for time complexity for encryption of plain text and decryption from cipher text with above existing algorithms.
