The Design for Secure DES_PA Algorithm with Protected Power Analysis
Zhigang Mao · Microprocessors · 2003
In this article, three theoretic methods are analyzed for protecting power analysis(PA),in which,the power randomization technology is the key,and the DES encrypt-algorithm is build by introducing MASK algorithm into it.And this kind of advanced DES _PA algorithm can increases the difficulty of PA attacks effetely,no matter software implementation or hardware implementation.At end, the correctness of DES _PA algorithm is validated using the Verilog-XL simulator from the Candence Company. With 0.25μm slow CMOS technology library,the result showed that the cell count of DES _PA module is about 1859,the maximize delay is 9.69 ns, and can be worked correctly under 100MHz,so that it is well suited to the field of smart card and the information security, and which would be meaningful for the field of industry.
