PKI是一个主要使用公钥密码算法来实现数据的机密性、完整性和防抵赖性的基础设施服务。访问控制的目的是要处理计算机和通信系统中的非授权信息。文章介绍了特权管理基础结构中的角色模型,并设计了角色属性中心,通过它对角色属性证书的管理实现了在PKI中的基于角色的访问控制模型,并分析比较了该模型与传统的访问控制模型的优缺点。
PKI is an infrastructure service that uses the public key cryptography algorithm primarily to achieve data confidentiality, integrity, and non-repudiation. The purpose of access control is to handle non-authoritative information in computers and communication systems. This paper introduces the role model in the infrastructure of privilege management and designs the role attribute center. Through the management of the role attribute certificate, it implements the role-based access control model in PKI, and analyzes and compares the model with the traditional access Control the advantages and disadvantages of the model.
