Abstract
Data security and privacy are essential for transmitting, storing, and preserving medical images. This article provides a secure chaotic framework for medical image encryption. The suggested technique has two stages: bit-level permutation and 2D SIM-based diffusion. The lossless technique is recommended for medical image encryption and decryption. It addresses the limitations of low-dimensional chaotic maps, such as small intervals and few parameters, and medical images’ unique texture and form. The keyspace of the new method is sufficiently big, and the encryption and decryption procedures are key-sensitive. Simulations and testing validate the new algorithm’s effectiveness and efficiency. According to security assessments, the algorithm is resistant to common attacks. A comparison of several encryption methods is performed. The proposed encryption method surpasses current encryption techniques when it comes to encrypting medical images.
