直接匿名证明（DAA）是一种实用、高效的认证证明协议，满足强隐私性要求。这个最近开发的协议已经被可信计算组采用，并包含在标准化的可信平台模块TPM中。本文表明，DAA的主要隐私目标，可以违反包括隐蔽身份信息。这个问题是非常相关的，因为隐私攻击既有效又很难检测。
Direct anonymous attestation (DAA) is a practical and efficient protocol for authenticated attestation with satisfaction of strong privacy requirements. This recently developed protocol is already adopted by the Trusted Computing Group and included in the standardized trusted platform module TPM. This paper shows that the main privacy goal of DAA can be violated by the inclusion of covert identity information. This problem is very relevant, as the privacy attack is both efficient and very difficult to detect.
