Advanced Encryption Standard (AES) is widely used symmetric cryptographic algorithm due to its ease in implementation on hardware and software. A number of works have been carried out on the reduction of power consumption of AES cores. Furthermore, the security of its implementation against side channel attacks also draws extensive attention. Various countermeasures that protect it from attack have been proposed. However not all of them is sufficient for high throughput applications. In this paper, we design and implement a differential power analysis (DPA) resistant AES core on Side-channel Attack Standard Evaluation Board. It is not only compact but also secure. The throughput is 2.56Gbps at 200MHz. By adding a set of registers and a random generator, the data-dependent encryption is hidden from observation. The experiments of DPA attack substantiate its effectiveness.
