Proposed Random Unified Chaotic Map as PRBG for Voice Encryption in Wireless Communication

It is well known that the wireless communications have great challenges in ensuring high security, due to the great facilities in attacking the communication channels. Hence there is continues trends towards finding a suitable approach to ensure high security for wireless communication. One of such approaches was with the application of chaos theory in cryptosystems. This paper provides a presentation for a proposed random Unified chaotic map as PRBG and its application in digital voice encryption. The proposed voice encryption system is testing with subjective and objective tests to check the performance of proposed random map. The test results are good. The simulation of the proposed scheme has been implemented using MATLAB (R2013a) programming language.
