This paper introduce a novel 3-dimensional discrete chaotic map. The calculated Lyapunov exponents of the map are 1.1638, 0.8946 and -0.2177. Numerical simulations show that the dynamic behaviors of the map have chaotic attractor characteristics. Based on the chaotic map and a chaos generalized synchronization (GS) theorem, a 6-dimensional chaotic GS system is constructed. Using the chaotic GS system...
Based on a stream encryption scheme with avalanche effect, this paper introduces a block encryption scheme with avalanche effect (BESAE), gives the definition of ideal block pseudo random number generators (BPRNG). Using any key stream generated by an ideal 2d word BPRNG with different seed to decrypt the ciphertext encrypted via the ideal BPRNG and the BESAE will generate an avalanche-liked text...
Recently, a stream encryption scheme using d-bit segment sequences has been proposed. This scheme may generate key avalanche effect. The randomness tests of d-bit segment pseudorandom number generator will be important for implementing such a scheme. Firstly this paper extends Beker and Piper’s binary pseudorandom sequence statistical test suite to d-bit segment sequences case. Secondly, a novel 3-dimensional...
