Kerberized Leasel Model For Grid

Rapid advancements in hardware have fostered the growth of Grid computing. Grids, formed from interconnection of clusters, provide behemoth amount of computing power. The technology assumes importance due to its ability to tap the unused computing power available in the distributed environment. Such a heterogeneous milieu is plagued by security concerns. Secure Group communication in the grid is a potentially critical concern with a broad scope for addressing the needs of a number of applications. Recently, it has come under the microscope of the researchers. Efforts have been made on proposing a highly secure, distributed, scalable and computationally efficient model for group communication in the grid environment. The proposed multicast security model satisfies the diverse security requirements of the multicast grid applications. The model is an adapted and strengthened version of LeaSel model, already proposed and proven for wired and Mobile networks. Kerberos is used for authentication.
