Speech encryption using finite precision chaotic maps based stream ciphers

Efficient and simple design of speech encryption-based stream cipher is produced and suggested in this paper with name finite precision chaotic map-based stream cipher (FPCM-SC) system. Two pseudo random bits generator (PRBG) are built by hybrid chaotic maps using finite precision format and named finite precision chaotic XOR based PRBG (FPCXOR-BRPB) and finite precision chaotic hopping based PRBG(FPCH-PRBG).
