Abstract: The concept of trusted computing was introduced. In particular, concerning the trusted computing principle of trusted computing platform alliance, the Trusted Platform Module (TPM) was expounded. The unique characteristics of data protection, Binding and Sealing, were tested. The test results show that the trusted platform's data protection capacity is obviously insufficient and the computing power of the trusted computing platform needs to be further improved.

Key words: trusted computing, Trusted Platform Module （TPM）, data binding, data sealing

摘要： 介绍了关于可信计算的概念，并特别针对可信计算平台联盟的可信计算理念,对可信平台进行了阐述。对可信平台模块（TPM）提供的独有特色的数据保护方式Binding和Sealing进行了测试，通过分析得出基本结论:可信平台在数据保护方面的能力明显不足，可信计算平台模块的计算能力有待于进一步提高。
