工作分析

On the base of deep understanding of its meanings and effect, we analyze the relation of campus culture and political guidance, and summavize the practical significance of enhancing the campus culture in military college, Subsequently we emplasize the important idea that campus culture is the very carrier of political guidance in military college. We give general comments on the current campus cultural activities in most military colleges, furthermore we point out the imperceptivity in the cognizance, decision and implement. Finally we make the following suggestions to deal with the cultivation of campus culture: to insure the correct direction of construction of campus culture, to foster the excellent cultural atmosphere in campus, to shape individual cultural characteristics of military colleges, to keep up the energetic sprit; to make good use of campus network, to bring up the campus cultural personnel.

The security of PKI system itself is especially emphasized during the system design and implementation process, which is in accordance with the pervasive characteristic of PKI. Second, the concept of a Trusted Key Management Center is introduced for the first time. This technology greatly strengthens key management practices and allows for smooth transition from PKI to Key Management Infrastructure. Third, certificate status mechanisms are investigated in depth, and a certificate revocation performance simulation system is devised. All these work will provide guides to practice and employment of PKI applications. Based on time constraints, a new taxonomy for authenticated dictionaries is proposed. Fourth, formal analysis ofOCSP protocol is carried out; then an efficient and scalable OCSP system is developed. Fifth, the special requirements caused by the working environments of Wireless PKI are analyzed. Based on communicative hashing and dynamic Merkle hash tree, an efficient certificate status validation method suitable for WPKI is presented. Sixth, one important kind of fair exchange protocols is studied, and a new CEMBS based on RSA cryptosystem is proposed. Afterwards, a novel fair exchange protocol totally based on RSA signature scheme is devised.
