DPA Resistance of Linear Component in Block Ciphers
-
Abstract
By mounting an actual DPA against FPGA implementation of SM4, the DPA resistance of linear component in SM4 has been discovered. Furthermore, the DPA resistance of linear component in block ciphers has been generalized, thus an algorithmic DPA countermeasures is proposed. This work also completes a successful DPA against a hardware implementation of SM4 for the first time.
