使用控制中属性更新与信息流行为安全性研究

Safety Survey on Attribute Update and Information Flow in UCON System

远程认证是可信计算基的重要组成部分,允许资源管理者通过制定严格的访问控制策略,建立安全、可信的远程客户端使用平台.该文深入研究了使用控制系统中属性更新行为和信息流行为两种远程认证行为,并从信息安全的角度系统地论证了如何通过这两种行为确保信息资源的安全性.

Remote attestation, which allows the challenger to establish the trustworthiness of a remote platform de- pending on its behavior, is an important integral part of Trusted Computing. In this paper, attribute up- dates and information flow have been described. The mechanism for attesting the dynamic behavior of UCON is proposed. From the point of Information security, the details regarding measurement, storage and verification of these behaviors in a trustworthy manner are presented.
