Abstract: Design of hardware encryption of military Godson computer is proposed. This novel method based on SRAM-based FPGA can be easily implemented without specific FPGA products. It can greatly enhance the system security and be convenient for the designer to choose FPGA products without constraints. Different encryption algorithms that can be used in this method are discussed for engineering selection purpose. And this method is finally applied in the design of military PC104 board based on Godson II.
