| 摘 要： | 针对TCG规范TPMv1.2的授权数据管理机制存在的管理复杂、密钥数据更新的同步问题,提出了一种新的授权数据管理方案,一个授权数据对应多个密钥对象,简化了管理复杂性,同时,构造授权数据列表,采用集中的授权数据管理方式,解决了密钥数据更新的同步问题,提高了TPM密钥管理的可信性和安全性. |
| 关 键 词： | 可信计算 密钥管理 授权数据 密钥对象 |

| Abstract: | The key management in the version 1.2 specification has an synchronization problem that attackers can access a key using the old authorization data which has been modified. And different keys in TPM should have different authorization data. The authorization protocols are complicated, and some of them have the same functions. The paper proposes a new method for the key authorization data management. Some entities in TPM may have the same authorization data. Therefore, the management of author- ization data becomes less complicated. The synchronization problem can be solved by the authorization data which improves the reliablity and security of the key management in TPM. |
