Abstract Number of cryptosystems based on chaos has been proposed, in recent years. Tao Xiang, Kwok-wo Wong, Xiaofeng Liao in 2008 proposed an improved scheme by using a symmetric key block cipher algorithm in which one-dimensional chaotic maps are used, in order to obtain chaotic sequences with better cryptographic feature. In this system, an encryption /decryption scheme was proposed, a cryptographic algorithm using one-dimensional chaotic maps and an external secret key. The chaotic map adopted in this cryptosystem is two logistic maps, and external secret key is of 128-bits. Based on the simulation result, more secure cryptosystem is proposed. As, two logistic maps are used in order to obtain chaotic sequences with improved cryptographic feature. All these advantages make this more secure cryptosystem for the use information transmission over insecure channel and secure application
