This paper presents a reconfigurable, high performance hardware implementation of highly secure biomedical image transmission system which can be used for sending medical reports in military and high security environments. The algorithm for encryption is based on DES algorithm with a novel skew core key scheduling. The encrypted image is not intelligible to an intruder, but the recovered image has high level of clarity. This type of encryption can be used in applications where we need to discourage eavesdropping from co-channel users or RF scanners. The biomedical image encryption technique is implemented on Virtex 5 XC5VLX110T Field Programming Gate Arrays (FPGA) technology and NET FPGA. Final 16- stage pipelined design is achieved with encryption rate of 35.5 Gbit/s and 2140 number of Configurable logic blocks (CLBs).
