Grid system security without public key settings

The Emerging E-commerce and high hit rate Web applications requires distribution of computational resources in a wide-area network with components administered locally and independently to provide faster response time to remote users. The dynamic and multi-institutional nature of these environments poses challenging security issues. Trust relationships among the communicating entities and faster access to resources are a major concern. Many researchers have proposed security protocols for grid system security based on Public Key Infrastructure (PKI), which needs huge computation resources. Few researchers like Chang et al, Das et al. etc. have proposed grid security protocols based on non public key settings which reduces huge computation processes but prone to mallicious attacks. In this paper we will propose a grid security protocol with out public key settings using light cryptographic operations like hash, XOR etc. which resists major cryptographic attacks and provides mutual authentication among the entities involved.
