英文摘要: Random numbers are important for a variety of applications, including encryption, secure key generation, gaming and Monte-Carlo calculations. As an important branch of quantum information science, randomness extraction based on quantum mechanics theory has attracted a great attention. Particularly, device-independent randomness extraction is of theoretical and practical significance. After the related works are studied carefuly, this project is aimed at investigating issues of device independent quantum randomness extraction, focusing on techniques of improving the efficiency and practical security of randomness expansion protocol, the design and analysis of randomness amplification, and the application of security evaluation methods in the security analysis of quantum key distribution. By the subject research, it is expected to have some creative achievements in efficient secure quantum randomness extraction, provided new ways and methods for related research and enrich the security analysis and evaluating system in quantum cryptography.
