FPGA-based modified chaotic system for speech transmission

Due the property of the chaotic systems by means of randomness, sensitivity to the initial values and large size of keys, chaos masking plays a vital rule in secure communication environment. The FPGA implementation provides low cost and high speed for chaotic communication systems. In this paper, a modified chaotic system with hyper chaotic behavior and key size of 2416 is proposed. Speech masking based on the modified chaotic system is...
