Grid Security and Trust Management Overview

Slavomír Kavecký

Security is one of the most important aspects in all grid environments. Researchers and engineers developed many technologies and frameworks used to establish an environment, in which users can use grid capabilities in a secure manner. In traditional grid environments security is based on user authentication and authorization of users actions on shared resources. However, this approach demands a pre-established trust relationship between the grid users and the resource providers. Security based on trust management enables dynamic creation of trust relationships between unknown parties. This article reviews various trust models designed for grid environments and lists their main characteristics and purpose in traditional and emerging grids.
