Talk on activities of security and grid computing service project

摘要

Summary form only given. With the rapid expansion of the GRID environment and the maturing of software technology such as multiagent system, systems that provide commercial services are faced with conventional commercial concerns, namely how to build trust between service owners and users. Authentication and authorization must be enforced on the use and provision of services. Based on our experiences, we introduce an authorization-based trust model (ABTM) (W. Wen et al., 2000) for such an environment, and then introduce a graphic-based authentication interface.
