    Chaotic Based Key Management and Public-Key Cryptosystem

    Public key cryptography is an emerging field whose cryptosystem is based on number theory. However, these cryptosystems suffer from problems such as dealing with large numbers and large prime numbers as well. A recent trend for public key cryptosystems is based on chaotic systems. In this paper a new system...
