Опубликована: Март 9, 2023

Due to the equivalent keys revealed by a chosen-plaintext attack or chosen-ciphertext attack, most of existing chaotic image encryption schemes are demonstrated be insecure. In order improve security performance, some scholars have recently proposed plaintext-related scheme. Although effect one-time pad is achieved, an additional secure channel required transmit hash values other parameters related plaintext before ciphertext can decrypted at receiving end. Its main drawback that absolutely needed information plaintext, which not feasible in practical applications. To further solve this problem, paper proposes scheme based on global dynamic selection multi-parallel structure. First, sequence employed dynamically select DNA encoding rules. Secondly, permutation with structure performed DNA-encoded matrix, and decoding rules selected according another sequence. Finally, diffusion obtained feedback mechanism introduced determine diffusion. Compared local schemes, advantage it realize selection, so as ensure there no key, resist does need practical. A theoretical analysis numerical experiments demonstrate feasibility method.

Physica Scripta, Год журнала: 2024, Номер 99(9), С. 095248 - 095248

Опубликована: Авг. 8, 2024

Abstract With the increasing frequency of data exchange, security transmitted information, especially images, has become paramount. This paper proposes a novel algorithm for encrypting grayscale images any dimension by using proposed fractional-order (FO) 4D hyperchaotic system, 2D Henon chaotic map permutation, and knight tour algorithm. Initially, sequences are generated utilizing FO which later employed to rearrange shuffle entire image pixels bolster efficacy encryption. To introduce an additional layer diffusion, permutation is used. Furthermore, applied starting from chosen point executing specified rounds on scrambled increase encryption’s robustness. The resultant encryption undergoes thorough testing evaluation. It exhibits high sensitivity key boasts larger space, rendering it more resistant brute-force attacks. demonstrates approximate correlation 0 between adjacent pixels. Further, size 256 × takes approximately 0.4 seconds, suitable cryptographic purposes.
