Current researches in image encryption techniques suggest using chaotic systems. But, one-dimensional (1D) chaotic schemes have drawbacks like small key space and weak security. This paper proposes a novel chaotic image encryption scheme based on two-dimensional (2D) logistic map. The 2D logistic map has more complex chaotic behaviors with respect to 1D logistic map like basin structures and attractors. The proposed scheme is based on permutation-substitution network and offers good confusion and diffusion properties in stream and block ciphers both. It encrypts plaintext image into random-like ciphertext image by generating the pseudorandom sequences from logistic map. The key schedule algorithm translates a binary encryption key to initial values and system parameters used in the 2D logistic map. This scheme uses 256 bit long cipher key for encryption/decryption. Experimental result indicates that the proposed scheme is secure against known cryptanalytic attacks and offers superior performance compared to existing chaotic image encryption schemes.
