Performance analysis of security certificate authority in P2P-based massive terrain navigation
基于P2P的海量地形漫游中安全认证性能分析*

The dynamic of peers in P2P overlay and their interactions had offered a challenge on security certificate authority.This paper proposed a new security certificate mode,namely P2P-PKI.P2P-PKI effectively broke a certificate into size-equal segments,and transmited and updated the segments among the dynamic peers.Theoretically analyzed the load of certificate authority and the time to certificate transmission and update.Simulation experiments are performed and the results show the out performance of P2P-PKI o...
