Direct Anonymous Attestation (DAA) is a cryptographic primitive which enables remote authentication of a trusted computer whilst preserving privacy of the platform's user. The protocol has been adopted by the Trusted Computing Group (TCG) in the latest version of its Trusted Platform Module (TPM) specification [ 1 ] to address privacy concerns ...

The Digital Advertising Alliance (DAA) establishes and enforces responsible privacy practices across industry for relevant digital advertising, providing consumers with enhanced transparency and control through multifaceted Principles that apply to Multi-Site Data and Cross-App Data gathered in either desktop or mobile environments.

直接匿名证明（Direct Anonymous Attestation，DAA）是一种技术，它允许一个平台（如物联网设备）证明其软件和硬件配置的合法性，同时不会泄露平台的身份信息。DAA技术通常用于安全通信，以保护用户隐私，防止跟踪，...

DAA（Direct Anonymous Attestation）是一种特殊的远程身份认证协议，该协议存在于具有可信模块的平台上。 DAA是一个签名方案，由TCG组织颁发其标准。 它名字源于： Attestation - 对来至于TPM的陈述进行证明。 1. 1对1的签名方案：即，普通的签名方案。 校验者可以根据签名者的认证公钥即可判断该签名的归属； 2. 1对N的签名方案：例如，环签名、指定校验者的签名、并行签名等。 这种情况下，校验者需要知道所有潜在签名者的认证公钥，即1对N； 3. 1对一组的签 …

2018年2月27日 · Direct Anonymous Attestation is a cryptographic scheme combining privacy with security. It uses the authenticator specific secret once to communicate with a single DAA Issuer and uses the resulting DAA credential in the DAA-Sign protocol with each relying party.

2015年1月1日 · Direct Anonymous Attestation (DAA) is a cryptographic protocol used to provide verifiable attestation for a computer platform with a TPM chip. The attestation is done by showing a signed authentication token to the verifier (e.g. service provider).

2014年1月1日 · Direct Anonymous Attestation is TPM2’s method of providing mathematically-proven anonymity or pseudonymity for signing keys in trusted platforms. The simple explanation of how DAA works is that it has a single verification (public) key but a plethora of signing...

Direct Anonymous Attestation (DAA) allows a small chip, the Trusted Platform Module (TPM), that is embedded in a host computer to create attestations about the state of the host system.

Direct Anonymous Attestation (DAA) is a cryptographic protocol used to pro-vide verifiable attestation for a computer platform with a TPM chip. The attes-tation is done by showing a signed authentication token to the verifier (e.g. service provider).
