6.3 Proposed System

The proposed system presents a Group KMS and a WRS. The KMS generates a common key to minimize the number of keys provided for effective authentication, whereas the WRS prevents various types of wormhole attacks. The following paragraphs demonstrate the designed concepts.

6.3.1 Key Management System (KMS)

For users who wish to participate in the Grid register via the Globus Toolkit (GT3) [4], the certificate authority issues a certificate embedded by a private key (Kid) to every individual Grid user. In the present cryptographic system, every user uses his private key for encrypting the data. For n user, n∗(n−1) number keys are employed. Since the Grid computing is a collaborative group environment, the most exclusive way of transmitting authenticated messages is by employing a common key among Grid users. The proposed work presents an effective key for Grid users. It minimizes the total number of keys employed in the Grid environment. The encryption and decryption process resembles Rivest-Shamir-Adleman (RSA) algorithm. The Group key provides an effective authentication and confidentiality service to the Grid environment [2].

Group key generation process: Let n be the number of Grid users.
