Abstract: Abstract: This paper addresses the issue of secure resource access control in pervasive environments. We study the requirements needed to deploy the access control platform and present a prototype implementation after having presented detailed design thoughts. Combination of PKI, PMI, PRBAC and RBAC are the cornerstone of proposed solution. Main motivation of our work is the absence of significant related work. The prototype implementation has been built and tested , the results are promising.

摘要： 摘要：本文针对普适计算环境中资源的安全访问控制问题。通过仔细分析开发这样一个访问控制平台的技术需求，在详细描述设计思想之后提出并实现了一个平台原型。RBAC、PRBAC与PKI、PMI模式的整合是整个工作的基础。进行这项工作的一个主要原因是由于相关领域研究的缺乏。对该原型平台进行了初步测试，结果良好。
