基于TPM的资源共享模型及访问机制

Research of Resource Sharing Model and Access Mechanism Based on TPM

传统的资源共享模式存在资源本身的不安全和过于简单的访问控制等问题,从而造成共享资源的恶意泄露.基于此,本文在传统资源共享模型的基础上,引入了可信平台模块(trusted platform module),利用TPM的安全数据存储功能对共享资源进行密封存储,并利用(usage control)模型对共享资源进行访问控制,从而构建了基于可信平台模块TPM的高度安全的层次化资源共享模型.

The traditional sharing pattern of resource is easy to cause the leaks malicious of the shared resource because of insecurity of resources and too simple access control.According to this,the paper introduces trusted platform module TPM based on traditional resource sharing model.The sharing resources are sealed to store by using TPM＇s function of secure data storage.Users can access to sharing resources by UCON model.And then the paper constructs a hierarchical sharing model with high security based on TPM.
