Secure mobile grid environment defeating wormhole attacks and scam users

The mobile Grid emerging as a successful technology in Grid Computing incorporates Laptops, PDAs and sensor devices into their network. As the technology develops the number of mobile-grid users tends to increase. The existing security work in Grid Computing is primarily focused on authentication and authorization of Grid service. It lacks to concentrate on malicious attacks that ensue during communication between resources. In this paper, we provide security considering various wormhole attacks and scam users in mobile grid environment. This method adopts group key management system for authentication and provides an efficient detection and prevention method for malicious Wormhole attacks. This security system presents an exceptional security to the data as well as the resources that participate in the grid.
