“…The audit condensed the conventional and present day strategies of voice/discourse encryption and exhibited the plausibility of receiving mayhem based cryptography for in remote correspondences. Musheer Ahmadet al [28], proposed a chaos based keystream generator for voice information encryption. The voice information bitstreams are encoded utilizing mixed key stream.…”

The biometric based crypto techniques extract the features from grayscale images and use those features in encryption process i.e., key will be generated from extracted features. In attribute based crypto-systems attributes of the user like email, usernames etc.…will be treated as a public key. Secret key is associated with each attribute i.e. for email there will be a secret key and for username there will be another secret key. In biometric based crypto systems, an access policy is built from the extracted biometric features.

“…PRBG must be designed with high quality of randomness and must be passing the most standards statistical randomness tests [10], Unpredictable with long period [11], low implementation cost and high throughput [12]. In the last years nonlinear dynamic system based chaos becomes more interesting for cryptosystem due to ergodicity, sensitivity to system parameters and initial 2153 conditions, aperiodic and random behavior with unpredictable nature [2,13].…”

“…In the last years nonlinear dynamic system based chaos becomes more interesting for cryptosystem due to ergodicity, sensitivity to system parameters and initial 2153 conditions, aperiodic and random behavior with unpredictable nature [2,13]. Chaos based speech encryption can be classified into analog like chaotic masking [1] and digital chaos like chaos based PRBG [11]. In the last years, different studies to generate Chaos based PRBG (CB-PRBG) were proposed: Addobbo et al in [14] used one dimensional chaotic map to generate PRBG and enhanced it using efficient post processing technique in [15].…”

Fixed point chaos based stream cipher (FPC-SC) is presented in this paper to encrypt the speech signal. Fixed point chaos based pseudo random bit generator (FPC-PRBG) is used as key sequence in stream cipher system. Two chaotic Lorenz and Chen systems are combined to generate Gold FPC-PRBG. The results show that FPC-PRBG has good statistical randomness and encryption performance measure and can be used to produce high speech security level. FPC-PRBG is implemented using Xilinx system generator (XSG) with Xilinx Virtex 4 FPGA device, the system is accessed routed in this device with throughputs 818.64,7978.88 and 780.24 Mbits/sec for Lorenz, Chen and Gold FPC-PRBG respectively, where 40 bits fixed point operation are used.

“…Pseudorandom binary sequences are widely applied to the various engineering domains such as biology system control, spread spectrum communications and cryptography [1][2][3]. Particularly, the security of cryptographic systems is strongly contingent on the pseudorandomness of the key stream [3].…”
