Differential power analysis (DPA) attacks find the correlation between power consumption and secret data in crypto-hardware. This letter proposes homogeneous dual-rail logic (HDRL), a standard cell DPA attack countermeasure that theoretically guarantees fully balanced power consumption and significantly improves DPA attack resistivity. Our experimental results on the AES S-Box circuit show that HDRL successfully prevents DPA attacks in all cases.
