“…Same with K-HF. It requires that the plaintext is independent of the corresponding hash value and that the ciphertext is highly sensitive [9]. Each bit in a binary hash expression is only 0 or 1, so the best hash function should be the initial value.…”

Chaotic systems are characterized by unidirectional, diffusive and initial value sensitivity of hash. Academia can use it to optimize algorithms for mathematical and computer encryption keys. This paper focuses on a hash function mixed chaotic system with a key. Then the state value and chaotic mapping relationship of the chaotic system are modified, and hash conclusions are obtained. Then the optimal design of messy technology with key hash is introduced briefly. A chaotic dynamic model with improved dynamic parameters is proposed to prevent chaos from affecting the speed and security of the algorithm. The results show that this method can effectively resist the attack of forging and peer keys. Moreover, the computation required by this algorithm is almost negligible.

“…The utilization of these techniques enhances both key sensitivity and the security of cipher images (Guesmi & Farah, 2020). The sine-Sine chaotic system is proposed and their chaotic sequence are utilized in permutation and diffusion architecture to encrypt color images, keys are generated based on Hash-based Cryptosystem (Huang et al, 2020). Idrees presented a cryptosystem that employs a substitution and permutation network along with a CBC mode of operation.…”

Sensitive images are being transmitted over insecure media as network and information technology evolve at a rapid pace. As a result, people are becoming more concerned about information security, specifically digital image protection. For securing digital images, numerous image encryption algorithms have been proposed. From that, a chaotic map has been proved a perfect image protection tool as it contains efficient random behaviour. This work proposes a novel two-dimensional sine-cosine map for developing an image cryptosystem. In the developed framework, at first, two random chaotic series are generated by the developed sine-cosine map, then the given image is divided into two blocks, and each block is confused by utilizing different chaotic key series. In the diffusion process, the chaotic series is first changed into integer form, which is applicable for executing some arithmetic operation between chaotic values and image pixels. In the diffusion phase, each confused image block pixel is converted into binary form, and a bit shifting operation is executed depending on the integer form of chaotic series. In the final process, a bit-xor operation is performed between the partial diffused image and chaotic series to obtain the final encrypted image. The proposed model's security strength will be evaluated using statistical and differential attack analysis.
