In this paper, a new one-dimensional fractional chaotic map is proposed and an image encryption scheme based on parallel DNA coding designed by using the map. The mathematical model of system combines sine fraction operation. Compared with some traditional systems, has larger range parameters better characteristics, which makes it more suitable for applications in information encryption. addition, algorithm proposed, overcomes shortcoming common coding-based algorithms. Parallel computing...
In order to improve the security and efficiency of image encryption systems comprehensively, a novel chaotic S-box based scheme is proposed. Firstly, new compound system, Sine-Tent map, proposed widen range performance 1D discrete maps. As result, system more suitable for cryptosystem. Secondly, an efficient simple method generating S-boxes proposed, which can greatly production. Thirdly, double algorithm By introducing equivalent key sequences {r, t} related with ciphertext, cryptosystem...
This paper proposes a new two-dimensional discrete hyperchaotic system and utilizes it to design pseudo-random number generator (PRNG) an efficient color image encryption algorithm. has very complex dynamic properties can generate highly random chaotic sequences. The characteristics of the are confirmed via bifurcation diagram, attractor, Lyapunov exponents, correlation analysis, approximate entropy permutation entropy. Compared with some traditional systems, larger range parameters more...
In the edge computing and network communication environment, important image data need to be transmitted stored securely. Under condition of limited resources, it is particularly necessary design effective fast encryption algorithms. One-dimensional (1D) chaotic maps provide an solution for real-time encryption, but most 1D have only one parameter a narrow interval, which has disadvantage security. this paper, new compound map composed logistic tent proposed. The system two parameters...
