Cryptography is now ubiquitous moving beyond the traditional environments, such as government communications and banking systems, we see cryptographic techniques realized in Web browsers, e-mail programs, cell phones, manufacturing systems, embedded software, smart buildings, cars, and even medical implants. Today's designers need a comprehensive understanding of applied cryptography. After an introduction to cryptography and data security, the authors explain the main techniques in modern crypt...

Abstract : This paper discusses some aspects of selecting and testing random and pseudorandom number generators. The outputs of such generators may he used in many cryptographic applications, such as the generation of key material. Generators suitable for use in cryptographic applications may need to meet stronger requirements than for other applications. In particular, their outputs must he unpredictable in the absence of knowledge of the inputs. Some criteria for characterizing and selecting a...

In this paper, new model of image encryption system using stream cipher based on fixed point chaotic maps are designed using Xilinx System Generator (XSG) in efficient way. Two Pseudo Random Bit Generators (PRBGs) depends on chaotic maps are proposed that are Fixed Point XOR Chaotic Map-PRBG (FPXORCM-PRBG) and Fixed Point Cascade Chaotic Map-PRBG (FPCCM-PRBG). The randomness tests in the National Institute of Standards and Technology (NIST) are used to test the randomness measures of the propose...

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). The statistical security analysis and speech residual unintelligibility measures are pr...
