A STUDY AND IMPLEMENTATION OF ENCRYPTION, WITH EMPHASIS ON CHAOTIC MAPS

The security of data transmitted over public communication networks and valuable data
storage have necessitated the need for very secure cryptography. Applications like video
teleconferencing, cable TV broadcast, etc use encryption extensively. Hence researches
for better ways of protecting data are still underway. And this project was aimed at
finding secure cipher by implementing Logistic Map Cipher for plaintext encryption and
decryption. The research was based on both symmetric ciphers and asymmetric ciphers.
The symmetric cryptosystem was chosenand finally implemented. In trying to implement
logistic map, Chaotic Maps were briefly analyzed and other types of encryption were
investigated in order to understand intensive and extensive applications of cryptography.
The three main parts of focus are keys' generator, the encryption and decryption parts,
which are the main steps before cryptanalysis can be carried out. In encryption, the
individual success of different parts will guarantee a complete cipher.
