A Novel Adaptive Proxy Certificates Management Scheme in Military Grid Environment [chapter]

Ying Liu, Jingbo Xia, Jing Dai
2007 Lecture Notes in Computer Science  
In order to apply GSI in Military Grid, a novel adaptive Proxy Certificates management scheme is brought forward based on the hierarchical one-way hash chains.  ...  Proxy Certificates (PCs) is one of key mechanisms in Grid Security Infrastructure (GSI). Users need PCs to access grid service. But there is no effective mechanism to manage the PCs in GSI.  ...  MG's overall concept is to enable data access for a variety of systems and users in the network no matter which military service owns a weapon system or where a user might be located around the world.  ...
