A new key generator algorithm based on sine map and SHA-3 for image encryption
In recent years, the need for secure cryptographic keys for various purposes has been constantly increasing. One of these areas is undoubtedly image encryption. In this study, a new key generation algorithm has been developed for use in image encryption algorithms. The proposed generator has a hybrid structure based on the chaotic sine map and the SHA-3 algorithm. It is aimed to produce strong keys by using the benefits of these two structures. To do this, first, bit sequences of the desired length are generated using the basic parameters of the sine map. Then, bit sequences of the same length are obtained using the SHA-3 algorithm. These two bit sequences are then subjected to an XOR operation to generate key values of the desired length. With this structure, 3 different bit sequences of 1 million length were produced. All of these bit sequences successfully passed NIST SP 800-22 tests. This key value obtained in this study has been successfully applied to a new image encryption algorithm. The results of the study demonstrate that the proposed algorithm meets important cryptographic criteria such as information entropy, correlation-histogram analysis, NPCR, and UACI values. In addition, the simple and fast structure of the algorithm in key generation was the most important difference from other studies.
Executive Impact Summary
The proposed key generator algorithm, combining the chaotic sine map and SHA-3, offers a robust solution for enhancing cryptographic security in image encryption. It successfully passed NIST SP 800-22 tests for randomness, demonstrating its strength against predictive attacks. Its efficiency and simplicity make it suitable for high-speed, secure key generation in various cryptographic applications, including IoT devices and one-time password systems, thus ensuring data integrity and confidentiality while being easy to integrate and deploy.

Cryptography is the practice and study of techniques for secure communication in the presence of adversarial behavior. It involves creating and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography utilizes advanced mathematical theories and computer science to secure information, providing confidentiality, data integrity, authentication, and non-repudiation. Key generation is a fundamental component, as the strength of encryption heavily relies on the randomness and unpredictability of the keys used. This paper's focus on a new key generator highlights its relevance to enhancing the foundational security of cryptographic systems, particularly for sensitive applications like image encryption.

Image Encryption Enhancement
The keys generated by this algorithm were successfully applied to an image encryption algorithm, demonstrating significant improvements in security metrics. The encrypted images exhibited information entropy values very close to the theoretical maximum of 8 (e.g., 7.9971 for Lenna R channel), indicating a near-perfect random distribution of pixel values. This makes brute-force attacks extremely difficult. Furthermore, high NPCR (0.9923) and UACI (0.3186) values were observed, confirming high sensitivity to minor input changes and robust diffusion properties. These results surpass traditional encryption methods by providing enhanced unpredictability and resistance against differential attacks, critical for safeguarding visual data in enterprise environments.
