摘要：Computational Grids is highly heterogeneous shared resources for problem solving in any dynamic environment. Accepting Grid computing technologies will be difficult, unless users are certain of safety of their data like in their own environment. Security in Computational Grids is in two folds. Security of the grid users ensuring authentication, confidentiality, integrity, single sign on and delegation on one hand and security of the grid resources in the form of authorization and access control on the other hand. Existing methods of authentication in computational grids have proved inadequate for identifying users, hence, a more reliable technique is required. This paper provides a model, which allows users reliable transactions in grid by using fingerprint to enhance security in grid. Thus, this study aimed at hybridizing fingerprint biometric and Attribute Based Access Control (ABAC) for authenticating and authorizing computational grid users based on attributes of the users for computational grid resources
