Research on the Security Problem of Mobile Agent in Grid Environment
Jingshan Shi, Xinghu Wang, Songyun Wang, Jie Yang · 2010
In this paper we present a dynamic programming mechanism combined with resource credit function based on D-S theory after analysing the programming of the mobile agent in grid environment. A mobile agent cooperates with credit schedule model in the grid virtual organization while transferring, therefore avoiding mobile agent being attacked by malicious agent platform. Due to the isomerism of the grid and the untrusted transfer relations between virtual organizations, there will appear a security leak while the mobile agent transfers between virtual organizations. This paper proposes a method for authenticating mobile agent based on chain of one-way signature function to carry out security authenticate by enabling trust relationships between agent platforms. It can avoid mobile agent platform being attacked by malicious agent in grid environment.
