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 (see also Loss of Internet anonymi
A Trusted Platform Module (TPM) is a secure cryptoprocessor that implements the ISO/IEC 11889 standard. Common uses are verifying that the boot process starts from a trusted combination of hardware and software and storing disk encryption keys. A TPM 2.0 implementation is part of the Windows 11 system requirements. [1]
Trusted Platform Module 2.0; CPU/chipset/BIOS support for S0ix "Low Power S0 Idle" power state; On Windows 8.1, supporting InstantGo and having a Trusted Platform Module (TPM) 2.0 chip will allow the device to use a passive device encryption system. [4] [5] Compliant platforms also enables full BitLocker Device encryption. A background service ...
More recent TPM versions (v2.0+) call for SHA-2. [ 1 ] [ 2 ] A desired characteristic of a cryptographic hash algorithm is that (for all practical purposes) the hash result (referred to as a hash digest or a hash) of any two modules will produce the same hash value only if the modules are identical.
This key is used to allow the execution of secure transactions: every Trusted Platform Module (TPM) is required to be able to sign a random number (in order to allow the owner to show that he has a genuine trusted computer), using a particular protocol created by the Trusted Computing Group (the direct anonymous attestation protocol) in order ...

EPID is an enhancement of the Direct Anonymous Attestation (DAA) algorithm. [6] DAA is a digital signature algorithm supporting anonymity. Unlike traditional digital signature algorithms, in which each entity has a unique public verification key and a unique private signature key, DAA provides a common group public verification key associated with many (typically millions) of unique private ...
A principal goal of the new consortium was to produce a Trusted Platform Module (TPM) specification compatible with NGSCB; the previous specification, TPM 1.1 did not meet its requirements. [19] [40] TPM 1.2 was designed for compliance with NGSCB [41] and introduced many features for such platforms. [42]
