On a Possible Privacy Flaw in Direct Anonymous Attestation (DAA) [PDF]
A possible privacy flaw in the TCG implementation of the Direct Anonymous Attestation (DAA) protocol has recently been discovered by Rudolph. This flaw allows a DAA Issuer to covertly include identifying information within DAA Certificates, enabling a colluding DAA Issuer and one or more verifiers to link and uniquely identify users, compromising user ...

An Improved Direct Anonymous Attestation Scheme for M2M Networks
AbstractThe remote anonymous trusted authentication of M2M equipments is a key problem in Internet of Things system. The Direct Anonymous Attestation (DAA) protocol had been adopted by TCG to implement the attestation of the trusted platform. Limited by the deficient computing and storing resources of most embedded devices, a new improved DAA (I-DAA ...
