This paper proposes a simplified AES algorithm resistant to zero-value DPA (differential power analysis) attack and its VLSI implementation. This paper makes some improvements to the additive masking AES algorithm to decrease its complexity. Moreover, such methods as module reuse and calculation order alteration are used to reduce chip area while maintaining its speed. Using the HHNEC 0.25mum CMOS process, the scale of the design is about 43K equivalent gates and its system frequency is up to 40MHz. The throughputs of the 128-bit data encryption and decryption are as high as 470Mbit/s
