An improved wireless grid security infrastructure based on trusted computing technology

Current grid computing has developed from traditional high performance, distributed and site-fixed computing to pervasive, ubiquitous and wireless computing. In practice, PKI-based solutions are introduced to solve security of grid computing. Because of limited computation power and limited memory spaces, it is difficult for wireless grid computing to gain secure solution in collaboration environment. The trusted computing (TC) technologies are introduced to offer great potential to improve this situation. In this paper, with treated trusted platform module (TPM) as a tamper-resistance module a TC-enabled architecture is proposed to improve wireless grid security. Especially authorization protection is discussed to demonstrate how to gain enhanced and distributed security in grid environment.
