A Secure BSS-Based Encryption Scheme Using AES Key Expansion Approach
Raziyeh Sadat Okhovat, Ali Sadr · ASME Press eBooks · 2011
In this paper, a secure BSS-based cryptosystem has been proposed for encryption of images. Conventional BSS-based encryption scheme is not secure especially against differential attack. The main reason is due to the fixed key which is applied to encrypt all images. Here we have exploited the AES key expansion to produce a different key for transmitting each confidential image. Our simulations and also calculations based on correlation coefficient confirm that the proposed algorithm has effectively enhanced the level of security.
