We propose a novel advanced orthogonal modulation format dark return-to-zero frequency shift keying/differential phase shift keying （DRZ-FSK/DPSK） and its realization scheme. The DRZ-FSK/DPSK is generated by the combination of a 40-Gb/s return-to-zero （RZ） signal and a DRZ signal which is converted from the RZ using a semiconductor optical amplifier （SOA） based on nonlinear cross polarization rotation （XPR） and then re-modulated by high-bit-rate DPSK at 40 Gb/s. The feasibility of the scheme is exper-imentally demonstrated. Bit error rate （BER） results of the total 80-Gb/s DRZ-FSK/DPSK orthogonal modulation signal with a subsequent 100-km single-mode fiber （SMF） transmission link show its potential for future high-speed long-haul optical communication.

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 200 MHz. 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.
