Secure image communication is becoming more and more important owing to stealing and content manipulation. To protect the confidential image from unauthorized access, encryption algorithms are considered. Due to the unique properties of chaotic systems, the admired encryption algorithm used is the chaos-based encryption algorithm. It deals with a 2D chaos-based encryption algorithm known as Two-Dimensional Tent Cascade Logistic Map (2DTCLM). Cascading, logistic map and tent map generate 2D-TCLM, which is applied on permutation and substitution stages to obtain an encrypted image from the original image. Simulation results show the effect of the proposed algorithm on DICOM images to obtain their corresponding encrypted and decrypted images to know the accuracy of transmission between end users. Performance metrics such as correlation, covariance, and histogram variance are analyzed to show that the transmission is possible in proficient mode.
