The information obtaining, processing and security guarantee capability are playing critical roles in comprehensive national power, and information security is related to the national security and social stability. Therefore, we should take measures to ensure the information security of our country. In recent years, momentous accomplishments have been obtained with the rapid development of information security technology. There are extensive theories about information security and technology. However, due to the limitation of length, this article mainly focuses on the research and development of cryptology, trusted computing, security of network, and information hiding, etc.展开更多

To know where the work is and where it goes, we focus on comprehensively surveying the twenty years of important fundamental research by Chinese scholars, and giving, from our point of view, the significance as well as the outlook of future work. Some of the reviewed work, including the researches on fundamental theory of cryptography, cryptographic algorithm, security protocol, security infrastructure and information hiding, greatly advances the related sub-fields, and is highly recognized in and outside of China. Nevertheless, the overall work, we think, is still facing the problems of unbalanced development of sub-areas, limited scope of research, lack of systematic work and application, etc., leaving much room for improvement in the near future.展开更多
