Implementation of a Chaotically Encrypted Wireless Communication System

Implementing the synchronization of chaotic systems presents new challenges that are difficult to handle by using currently adopted schemes. The paper proposes an implementation of a synchronization method for a pseudo-True Random Bit Generator (PTRBG) based on chaotic systems. Synchronization of the chaotic binary sequences is achieved by using the backward iteration approach. The implementation test bed for the complete wireless communication system is based on a Chipcon wireless development kit. Assessment of the pseudo- true random bits (PTRB) generated is performed using the NIST statistical test suite.
