Abstract

A cryptosystem is a family of uniquely reversible transformations from a set of plaintexts into a set of cryptograms. A private key cryptosystem uses a key exchanged by some secure means between two users, the possession of which enables both of them to encrypt and decrypt messages sent between each other. In this paper, we introduce a new application of chaos in cryptography. The main idea is to use one-dimensional (1-D) chaotic map to construct a private key block cryptosystem.
