The main objective of this research paper is to analysis on the improved performance of ANN based chaotic generator. We are analyzing the performance of chaotic generator model during encryption and description and produced outcomes compare with earlier published work scenario. In this work Encryption and decryption of binary value has been completed by the same value. Chaotic neural network algorithm used for producing the random chaotic sequence.[1][2] Produced random chaotic sequence value is the encrypted binary ASCII values of A to Z sequence of original ASCII Code binary value, with a same initial parameter. This paper provides a review on the use of improved the performance of ANN based chaotic generator and provides high range of security in the field of cryptography.
