可信计算平台数据维护技术的研究与实现

在可信计算平台的维护过程中，需要保证保护数据的完整性，安全性和可用性。针对该需求，首先分析了在可信计算平台中的密钥及其使用方法，描述了在维护过程中需要
转移的数据，并提出了一种安全的维护方法。该方法在进行维护操作的源平台所有者、目的平台所有者，TPM 生产厂商和第三方可信机构四个角色参与下，利用TPM 的安全特性，保证了维护过程的安全。

Abstract：In the maintenance process on the trusted computing platform,the integrity,
security and usability of the protected data must be ensured. According to the requirement,
the key on the trusted platform and its usage is analyzed, the data need to be moved in the
maintenance process is discussed, and a secure maintenance method is presented. Under the
charge of four roles in the maintenance process: the owner of the source platform, the owner
of the destination platform, the TPM manufacturer, TTP, this method utilize the security
characteristic of TPM to guarantee the security of the maintenance process .
