L-DAA: Lattice-Based Direct Anonymous Attestation
Lattice based cryptography Direct Anonymous Attestation Universally Composable security model
2018/5/3
Direct Anonymous Attestation (DAA) is an anonymous digi- tal signature that aims to provide both signer authentication and privacy. DAA was designed for the attestation service of the Trusted Platform...
In TPM2.0, a single signature primitive is proposed to support
various signature schemes including Direct Anonymous Attestation
(DAA), U-Prove and Schnorr signature. This signature primitive
is imp...
DAA-TZ: An Efficient DAA Scheme for Mobile Devices using ARM TrustZone
DAA Privacy Mobile Devices
2015/12/29
Direct Anonymous Attestation (DAA) has been studied for
applying to mobile devices based on ARM TrustZone. However, current
solutions bring in extra performance overheads and security risks when
ad...
Lightweight Anonymous Authentication with TLS and DAA for Embedded Mobile Devices

2011/3/10
Although anonymous authentication has been extensively
studied, so far no scheme has been widely adopted in practice. A particular
issue with fully anonymous authentication schemes is that users

Direct anonymous attestation (DAA) is a special digital sig-
nature primitive, which provides a balance between signer authentication
and privacy. One of the most interesting properties that makes t...

Direct Anonymous Attestation (DAA) is an anonymous digital
signature scheme that aims to provide both signer authentication
and privacy. One of the properties that makes DAA an attractive choice
in...
In [17, 18] we presented a pairing based DAA protocol in the asymmetric setting, along
with a “security proof”. Jiangtao Li has pointed out to us an attack against this published protocol,
thus our ...
A successful strategy was identified for any Verifier colluding with any
Issuer to distinguish honest Provers issuing DAA signatures. An additional
verification equation was introduced for a Prover ...
