A symmetric key cryptographic technique based on frame rotation of an even ordered square matrix

Abstract

A session based symmetric key cryptographic technique has been proposed in this paper. It considered the plain text as a stream of finite number of binary bits. Using frame rotation technique of square matrix, input bits are oriented to generate cipher text. A session key is generated from the plain text information. Results are generated to compare the proposed technique with Triple-DES (168 bits), AES (128 bits) with respect to different parameters.
