Hardware Implementation of Biomedical Data Encryption using FPGA

If privacy is outlawed, only outlaws will have privacy. Maintaining privacy in our personal communications is something everyone desires. Without encryption, it would be very easy for sensitive data to be stolen and used malevolently. This paper presents AES encryption algorithms and a comparison between them and other encryption algorithms such as DES, RSA, and Blowfish. It also presents some statistical tests which test the randomness of the used key. A hardware implementation of the AES on the recent Xilinx Spartan-6 FPGA is applied on text and biomedical images. Such device is to speed up the AES algorithm and to reduce logic area. In addition, the comparison between FPGA and Matlab is introduced.
