英文摘要： The high-speed true random number generators (TRNGs) based on the chaotic semiconductor lasers, and their potential applications in the optical chaotic communication systems, are fundamental researches. The high-speed random sequence are widely used in many cross fields, such as communication and information systems, signal and information processing, and in information security. This work refers to semiconductor laser technology, optical chaotic communication and TRNGs. Different from the conventional pseudo random number generators (PRNGs), this work starts from the latest research progress of TRNGs based on the chaotic semiconductor lasers, and investigates the novel techniques for generation of high-speed random sequence, the evaluation for the randomness, as well as the potential applications of the TRNGs. Two typical schemes are considered for generation of random number. Based on the prototype TRNGs, we firstly establish and develop the novel techniques to achieve random number, and then discuss the practicality and the security of TRNGs. Besides, we also study the degradation of the chaotic sequence, and explore the effective schemes to achieve performance-enhanced random numbers. In particular, by introducing the signal processing technology to quantitatively evaluate the practical optical chaotic seque
