Abstract: The differential power analysis (DPA) has become a big threat to crypto chips since it can efficiently disclose the secret key without much effort. Several methods have been proposed in literatures to resist the DPA attack, but they largely increase the hardware cost and severely degrade the throughput. In this brief, a security problem based on ring oscillators is resolved by a new architecture with self-generated true random sequence. The true random-based architecture is implemented with an Advanced Encryption Standard (AES) crypto engine using UMC 90-nm CMOS technology. The DPA-resistant AES engine can achieve 2.97-Gb/s throughput at an operating frequency of 255 MHz with a 0.104-mm(2) cell area. The proposed DPA countermeasure circuit has only 6.2% area and 18.5% power overhead without throughput degradation.
