A New Encryption Method Using Chaotic Logistic Map

Encryption is to rearrange the message into difference form so that the message is keep secret. The goal of encryption is to provide an easy and inexpensive means of encryption and decryption to all authorized users in possession of the appropriate key and difficult and expensive means to estimate the plain text without use of the key Nowadays the Internet becomes popular and encryption technology becomes essential to everyone. Traditional encryption methods such as DES, RSA etc are widely used today and it seems to be computationally secure [1]. The Baptista proposed a Chaotic Encryption Method, which seems to be much better than traditional encryption methods used today [1]. Chaotic encryption is the new direction of cryptography. It makes use of chaotic system properties such as sensitive to initial condition and lot of information. But it still has several problems, such as slow in speed and suffering from floating point operations and has less security. This project is to overcome these problems so that this technique is applicable [3]. The purpose of this project is to learn the method to use chaotic function in security purpose. Thus we can say that the technique of this encryption method for images and data are .more secure as compare to previous encryption method and we are sure that this technique is much more secured and enhanced the security.
