Abstract

Number of cryptosystems has been proposed in recent years that are based on chaotic maps. Nisha Khushwah in 2013 proposed an improved symmetric encryption scheme using one dimensional chaotic map in order to obtain chaotic sequences with better cryptographic features. In this proposed system for encryption/decryption the two different chaotic maps are used with a 128 bit external key. Based on the simulation result, more secure cryptosystem is proposed. As two chaotic maps, one skew tent and one logistic map are used in order to obtain chaotic sequences with better cryptographic features.
