In the realm of intelligent systems, vast amounts of sensitive images are generated and transmitted, such as medical scans, real-time robotic feedback, and beyond. Various systems have been developed to secure and maintain the integrity of this sensitive data. However, existing image cryptosystems often exhibit vulnerabilities to data loss, limited processing speed, and susceptibility to potent attack strategies like differential and chosen-plaintext attacks. Motivated by the intricate mechanisms of rotary combination locks, image tiling, and chaos theory, this paper addresses these shortcomings by proposing new techniques that enhance the security and integrity of real-time systems. The first part of the article introduces a novel one-dimensional chaotic map termed 1D-RSS, built upon the reciprocal and squared sine functions. Extensive evaluation of 1D-RSS reveals its intricate chaotic behavior, characterized by an infinite chaotic range and high sensitivity to initial states. The second part leverages the 1D-RSS map to design a new image encryption system founded on three main contributions: Preservation Image Tiling (PIT), Sensitive Private Diagonal Substitution (SPDS), and Rotary Combination Permutation (RCP). PIT is a novel image processing technique designed to resist data loss attacks, crucial for recovering sensitive data like medical images. SPDS grants the system immunity to various attacks, including chosen-plaintext and differential attacks. RCP is a new permutation process that breaks the correlation between pixels based on the rotary combination mechanism. Moreover, the experiments demonstrated that the proposed system offers robust security and resilience with a fast running speed, making it ideal for securing real-time applications. •A new image processing technique is proposed to resist data loss attacks.•Designed a new technique that grants the system immunity to various attack types.•A novel rotary combination permutation is proposed to break the pixel correlations.•Designed a new chaotic map that exhibits infinite chaotic range and high sensitivity.•Developed a new method that offers robust security and resilience with fast speed.
