For country who is going to strengthen network construction like China,it is an important fundamental supporting technology worth researching. China is in the international forefront in the field of trusted computing. This paper gives comprehensive introductions to the new development and application of key technologies in trusted computing,such as various trusted platform modules(TPM、TCM、TPCM),TCG Software Stack(TSS),trusted cloud server and Trusted Execution Environment(TEE). We illustrate the progressing and application extension of these technologies and also point out some key problems worth studying in the future.展开更多

This paper surveys the theory and technology of trusted computing. The development history of trusted computing, and the development of trusted computing in China are introduced in this paper, and then it analyzes some problems of trusted computing at present which are delay in theory research, some key technologies to be developed and lack of trusted software system. Some fields are worthy to be explored on are pointed out including key technology, basic theory and application in trusted computing.展开更多

Lots of our recent researches have been integrated in this architecture. And the main current researches in the related area have also been absorbed. The main attention of this paper was providing a compact and realizable method to apply ubiquitous computing into our daily lives under sufficient secure guarantee. At last,the personal intelligent assistant system was presented to show that this architecture was a suitable and realizable security mechanism in solving the ubiquitous computing problems.展开更多

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
