密码协议和算法若干问题研究:理论及应用

Cryptographic protocols and algorithms play a central role in moder cryptography. This project covers a list of key problems in theory and applications of cryptographic protocols and algorithms, including theory foundations of cryptographic protocols and algorithms, zero-knowledge, encryption, signatures, core key-exchange protocols for network security, and security and privacy of RFID authentications, etc. Theory research of this project pays first importance on creating new areas (notions, frameworks, etc), and on systematic and framework nature of research works. Theory research aims for obtaining, via original creativity, systematic and fundamental research outputs. This project is featured by its close tie between theory and practice, by its close tie among industry,education and research, and by its focus on transorming knowledge rights into productivity. Based on the theory works of this project, we will develop innovative new technologies and building tools for applied cryptographic protocols and algorithms, obtain important technology innovations and a list of independent knowledge rights and patents in cryptographic applications. With the developed new applied technologies and knowledge rights, we will actively take part in the competition for next generations of international standardizations of some related cryptographic protocols and algorithms. Through cooperations with industry and organizations, we will do best to transform our applied technology into productivity, in order to make some essential contributions to national knowledge economy development and to the independent innovations on core information security technologies.
