Abstract : The paper presents a bit-level chaos based color image encryption technique using Logistic-Sine-Tent-Chebyshev (LSTC) map. The color image is first decomposed into red, blue, and green color image components. Each color image component is transformed to an 8-bit binary plane. Mutual diffusion of two sequences is used to scramble two binary elements using the LSTC map, cyclic shifts, and the XOR operation. The binary element confusion is performed using a chaos map and transformed into binary bit planes. With the help of the chaos map, the binary element is swapped and transformed into another binary bit plane. Individual cipher text image components are obtained by combining the binary bit planes. Finally, the encrypted image component is combined to generate the color cipher text image. The proposed scheme experimental results show excellent resistance to statistical attack, differential attack, and brute-force attack with a single round of encryption. As a result, the proposed scheme is secure and reliable for transmitting color images over the internet.
