“…They can be generated by the internal functions defined in advance. By means of the transform ( ) y a b a x    , a uniform distribution random matrix can be obtained in the arbitrary interval [ , ] a b , where the random variable x satisfies the uniform distribution in the interval [0,1] . Similarly, the formula y x     can be used to generate the random numbers with the mean and variance of  and 2  respectively, where x obeys the standard normal distribution.…”

Abstract. Both the random matrixes generated by MATLAB and the element-by-element matrix operations in MATLAB are proposed to construct the pixels sequences encryption algorithm of Images. The random matrixes which obey the uniform distribution or normal distribution are used to generate the key stream. By running the element-by-element matrix multiplication and division between the pixels matrix and the key matrix, the sequences of pixels are encrypted and decrypted. This algorithm shows such advantages as good security, simple calculation, and easy availability for programming. Furthermore, the feasibility and stability of the algorithm are demonstrated by experiments.

“…On the other hand, chaotic system has attracted tremendous interest from researchers thanks to its good features, such as ergodicity, pseudo-randomness and sensitivity to initial conditions and control parameters, which are in line with the basic requirements, like confusion and diffusion, in cryptography [2,3]. These good chaotic properties make chaotic systems potential for constructing cryptosystems in multimedia field [3][4][5][6][7][8].…”
