摘要
SPKI/SDSI是一种灵活且可扩展的分散的安全模型,它能够提供认证、保密和访问控制。然而,SPKI/SDSI证书链并不适合大规模、高动态的环境,比如计算网格。通过观念模型基于主观逻辑对SPKI/SDSI安全模型进行了扩展,提出了一种扩展的SPKI/SDSI模型。该扩展模型可以灵活应用于计算网格。
SPKI/SDSI is a flexible and extensible decentralized security model that provides authentication,confidentiality, and access control.However,SPKI/SDSI certification chains are not suitable for large scale,highly dynamic environments such as computational grids.This paper extends the SPKI/SDSI model by including an opinion model based on subjective logic.The model can be flexibly applied to computational grid.
