Security Scheme for Cross-Domain Grid: Integrating WS-Trust and Grid Security Mechanism

A federated security scheme based on WS-Security standard for cross-domain grid is proposed. It integrates the WS-Security standard and the grid security mechanism. A trust model is established based on WS-Trust specification. A communication is established based on WS-SecureConversation specification. The architecture is implemented in a SAML-based federated authentication and authorization cross-domain Grid. Through experiment and analysis, it is shown that our scheme is secure, effective and efficient.
