TWO-STEP MOBILE AGENT BASED AUTHENTICATION ARCHITECTURE:TOWARDS EFFECTIVE GRID AUTHENTICATION

基于移动代理的双重认证:一种高效的网格认证体系结构(英文)

The grid technology is recognized as the next generation of Internet and becomcs the center of recent researches in the computer society. Security is one of the most crucial issues to address in Internet and is of the same importance in the application of grid technology. As a critical component of grid security, the secure authen- tication needs to be well studied. In this paper, a two-step mobile agent based（TSMAB） authentication architecture is proposed based on Globus security infrastructure （GSI）. By using mobile agent （MA） technology, the TSMAB authentication architecture is composed of the junior-authentication and the senior-authentication. Based on the design and the analysis of TSMAB model, the result shows that the efficiency of grid authentication is improved compared with the GSI authentication.

网格技术作为下一代Internet技术,已逐渐成为计算机领域研究的重心之一。作为网格安全的重要组成部分,安全认证是一重要环节。因此,在客观分析了GSI(Globus security infrastructure)认证结构的基础上,针对其存在的问题与不足,采用了移动代理技术进行改进,提出了一种基于移动代理的双重(Two-step mobile agent based,TSMAB)网格认证体系结构。该结构通过移动代理技术实现了初级认证和高级认证两个阶段。通过对模型的设计与分析得出:TSMAB认证体系结构提高了原有GSI认证的效率。
