Power analysis research and DPA implementation of AES cryptography based on FPGA

Differential Power Analysis(DPA) is cracked AES cryptographic algorithm most effective a attack technology,to prevent this kind of attack technology based on FPGA build experimental platform to achieve AES encryption algorithm,based on this attack DPA stands on through the mask technology and mask technology AES encryption algorithm to optimize and improve.Through the experiment proved that the improved algorithm can effectively prevent the AES DPA stands against.
