Because of the coexistence of multi-PKl in multi-domains of active networks, the implementation of authentication for such multi-domains becomes one of the most important issues in active network security. This paper proposes an authentication model and designs a suit of protocols to tackle this important issue. The proposed model supports mutual entity authentication between multi-type domains and is suitable for practical implementation of authentication in active networks.

Because of the coexistence of multi-PKI,how to implement authentication for multi-domain would become one of the most important problems on active network security.This paper proposes an authentication model and designs a suit of protocols to satisfy these actualities.The model which supports cross-domain mutual entity authentication is very suitable for the practice of authentication on active network.

基于DMR(Double modular redundancy),提出了DVS(Dynamic voltage scaling)技术与比较存贮检测点(CSCP)、存贮检测点(SCP)、比较检测点(CCP)三类检查点的集成方案.同时应用概率知识分别导出该方案完成实时任务所需的平均执行时间,以及使平均执行时间最短的最佳检测点数.最后,通过实例对采用DVS技术前后系统的性能进行了分析和比较,验证了本方案的优越性.
