An Identity-Based Authentication Model for Multi-Domain Grids
Dengguo Feng · Dianzi xuebao · 2006
We consider the efficient authentication for Grids.We analyze the problems of existing Grid authentication frameworks,and propose an identity-based authentication model for multi-domain Grids.Our model is based on the identity-based PKI so as to overcome the problem of low efficiency and high cost posed by traditional certificate based PKI.Moreover,our model supports cross-domain mutual entity authentication,which is necessary to common Grids consisting of distinct domains.Through simulation testing,it is shown that our model is more efficient and more lightweight than those frameworks based on traditional PKI.It is also shown that due to supporting cross-domain authentication,our model is more suitable for Grids than framework proposed by W.Mao,which can only work in a single domain.
