Security architecture for a service-oriented learning assessment grid
Xu Jun · Journal of Tsinghua University(Science and Technology) · 2005
Security is a challenging issue in grid systems.A service-oriented security architecture was developed to provide security in learning assessment grid(LAGrid),an e-Learning oriented grid system.A symmetric key infrastructure was used in for single sign on enabled authentication and role-based authorization.A security token service was designed to give message-level encryption and signature mechanisms.The service-oriented security architecture has been successfully implemented in LAGrid system which supports wide-area resource sharing and large-scale cross-organizational collaborative work.In addition,the system provides a secure,transparent and web-based user environment.
