A Novel Authentication Architecture for Grid Security

The grid security infrastructure (GSI) has been accepted as the primary authentication mechanism for the Grid. However the efficiency of the grid system is still required improvement because exchanging certificates and verifying validity are compulsory in the authentication procedure. In this paper, we propose a novel authentication architecture for grid Security (AAGS), which adopts seeded secret key and combine key technique and employs the features of conic curves over the residue class ring Z_n into the authentication security, and we give precise definitions of the grid infrastructural protocols for AAGS. Compared with the SAP (SSL Authentication Protocol) in the GSI, AAGS is more efficient and convenient for its implementation, which contributes to the larger grid scalability and may be regarded as an optimized authentication approach of the grid security infrastructure.
