Implementation of correlation power analysis attack on an FPGA DES design

Differential power analysis (DPA) has become a great threat to cryptographic chips as an important side channel attack. But it is still not easy to put attacks on encryption algorithm with FPGA implementation. In this paper, a data encryption standard (DES) algorithm is implemented on a FPGA. Then an experimental platform of DPA for FPGA implementation is built with verified feasibility. Experimental results for correlation-based DPA attack on the DES hardware implementation show that our DPA experimental platform is effective in realising the DPA attack on hardware implementation of cryptographic algorithms.
