由于网格环境的复杂性和网格计算的特性,使得网格提出了更高更广泛的安全需求,安全的认证是实现这一需求的关键部分。基于虚拟组织的网格安全认证体系正是为了满足网格计算和安全的特殊需要而提出的。通过统一建模语言UML,详细阐述了基于虚拟组织认证的关键技术,对进一步完善网格环境下采用虚拟组织中的分布式管理的安全实现具有较大的实用价值。
Grid environments have a broad range of security requirements that differ from conventional network environment needs. The certification is the key part of these requirements. The certification based on virtual organization just aims at the especial requirement of computing and securing in this kind of large- scale grid environment. In this paper, methods of UML in system are studied, and the modeling process and key techniques of using UML in the certification based on VO are described. It has the significant and practical value to perfect the secure realization using distributed management of virtual organization.
