Progress and Prospect of Some Fundamental Research on Information Security in China

With the development of network and informationtechnologies, information security is more and more widely researchedin China. To know where the work is and where it goes, we focus oncomprehensively surveying the twenty years of important fundamentalresearch by Chinese scholars, and giving, from our point of view, thesignificance as well as the outlook of future work. Some of thereviewed work, including the researches on fundamental theory ofcryptography, cryptographic algorithm, security protocol, securityinfrastructure and information hiding, greatly advances the relatedsub-fields, and is highly recognized in and outside of China.Nevertheless, the overall work, we think, is still facing the problemsof unbalanced development of sub-areas, limited scope of research, lackof systematic work and application, etc., leaving much room forimprovement in the near future.
