We propose a novel image encryption algorithm based on two pseudorandom bit generators: Chebyshev map based and rotation equation based. The first is used for permutation, and the second one for substitution operations. Detailed security analysis has been provided on the novel image encryption algorithm using visual testing, key space evaluation, histogram analysis, information entropy calculation, correlation coefficient analysis, differential analysis, key sensitivity test, and computational and complexity analysis. Based on the theoretical and empirical results the novel image encryption scheme demonstrates an excellent level of security.

An encryption scheme for colour images using a spatiotemporal chaotic system is proposed. Initially, we use the R, G and B components of a colour plain-image to form a matrix. Then the matrix is permutated by using zigzag path scrambling. The resultant matrix is then passed through a substitution process. Finally, the ciphered colour image is obtained from the confused matrix. Theoretical analysis and experimental results indicate that the proposed scheme is both secure and practical, which make it suitable for encrypting colour images of any size.

“…In [19] an efficient way is proposed to generate a De Bruijn sequence by extending a maximal-length LFSR with n stages. The proposed approach could be also used to encrypt images based on chaotic maps [20]. Poluyanenko [21] proposed an approach based on FPGA.…”

Nonlinear feedback shift registers (NLFSRs) have received much attention in designing various cryptographic algorithms such as stream ciphers and light weight block ciphers in the provision of high-level security in communication systems. The main purpose of NLFSRs is to generate pseudorandom sequences of bits. NLFSRs are known to be more secure than their linear counterparts. However, there is no mathematical foundation on how to construct an NLFSR with optimal period. In this paper, we propose a new type of NLFSR function of degree 2 with optimal periods. Using our construction method, we propose 639 new functions of this type with optimal periods.
