For the smart card chip in the power leakage problem in the process of DES encryption, we put forward accumulative attack algorithm and segmented attackalgorithm on DES encryption with back and forth random round which based on the analysis of DPA attack on general smart card and the features of random round, and get all keys rightly and successfully, to prove back and forth random round can’t protect security of smart card. At last, by comparing the two algorithms, we give the scope of them.
