An energy efficient AES engine with DPA-resistance

[摘要] (cont.) The secured core has been subjected to 100K encryptions, 33x more than the number of runs at which attack can disclose a secret key of the unprotected core, but none of its secret key have yet been disclosed. When running the encryption core at 0.4V and 10IMHz, power increases by 2x compared to the unprotected core. Maximum throughput at 1.OV is reduced by 2/3 for protected core compared with the unprotected core. This IC performance overhead comes at the cost of the increased security.
