An Efficient Modified Advanced Encryption Standard (MAES) Adapted for Image Cryptosystems

Security in transmission storage of digital images has its importance in today's image communications and confidential video conferencing. Advanced Encryption Standard (AES) is a well known block cipher that has several advantages in data encryption. However, it is not suitable for real-time applications. In this paper, we present a modification to the Advanced Encryption Standard (MAES) to reflect a high level security and better image encryption. The modification is done by adjusting the ShiftRow phase. Experimental results verify and prove that the proposed modification to image cryptosystem is highly secure from the cryptographic viewpoint. The results also prove that with a comparison to original AES encryption algorithm the modified algorithm (MAES) gives better encryption results in terms of security against statistical attacks.
