网格安全模型中关键策略的研究

Research of Pivotal Policy in Grid Security Model

给出了一个独立于平台的网络安全模型,并对网络安全模型中的认证和授权等关键策略作了分析。这些关键策略包括:基于桥接CA(认证中心)的PKI(公钥基础设施)管理方式、基于虚拟组织的认证策略、网络环境中委托授权的访问控制策略等。采用这些策略有利于不同PKI管理策略的虚拟组织之间认证,简化了网格的安全认证,能够对网络资源进行动态有效地管理。

A platform-independent grid security model and several model-based security policies such as authentication and authorization are presented in this paper.The security policies include the public key infrastructure(PKI) management model based on bridge certificate authority(CA),the authentication policy based on virtual organization and the access control policy such as delegation in grid environment.These policies can facilitate authentication among virtual organizations based on different PKI management policies,simplify security authentication in grid environment,and manage grid resources dynamically and effectively.
