This paperpresents a reconfigurable, high performance hardware implementation of highly securebiomedical image transmission system which can be used for sending medical reports in military and highsecurity environments. The algorithm for encryption is based on DESalgorithm with a novel skew core keyscheduling. The encrypted image is not intelligible to an intruder, but the recovered image has high level ofclarity. This type of encryption can be used in applications where we need to discourage eavesdroppingfromco-channel users or RF scanners. The biomedical image encryption technique is implemented onVirtex 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/sand 2140 number of Configurablelogic blocks (CLBs)
