Abstract

The importance of digital media has been increased in this pandemic; the security of the media generated is huge issue. This led to development of cryptographic techniques that are secure and fast. Chaotic image encryption is gaining popularity considering its ergodic properties. In this paper a 3-dimensional chaotic logistic map cryptography based on iterations with three parameters is proposed, the generated chaotic sequence is mixed with the key. The new sequence is used for scrambling and diffusion of pixel values of image. The result was evaluated by using many measures like NPCR, UACI, MSE, Key sensitivity analysis. The demonstrated result shows the proposed scheme is reliable and is resistant to differential crypto analysis attack.
