Digital signature is a fundamental primitive with numerous applications. Following the
development of pairing-based cryptography, several taking advantage of this setting have …

Coconut is a novel selective disclosure credential scheme supporting distributed threshold
issuance, public and private attributes, re-randomization, and multiple unlinkable selective …

Abstract Direct Anonymous Attestation (DAA) is a cryptographic protocol for privacy-
protecting authentication. It is standardized in the TPM standard and implemented in millions …

Abstract Intelligent Transportation Systems (ITS), the heart of the new revolution of smart
transport, has evolved from the well-known Vehicular Ad hoc Networks (VANETs) to become …

Trusted Platform Modules (TPM) are multipurpose hardware chips, which provide support for
various cryptographic functions. Flexibility, scalability and high performance are critical …

Abstract Direct Anonymous Attestation (DAA) is one of the most complex cryptographic
algorithms that has been deployed in practice. In spite of this and the long body of work on …

The Trusted Platform Module (TPM) is an international standard for a security chip that can
be used for the management of cryptographic keys and for remote attestation. The …

The objective of direct anonymous attestation (DAA) is to enable a party to prove that the
party is a member in good standing in a group without revealing information about its …

Abstract Direct Anonymous Attestation (DAA) is an anonymous signature scheme designed
for anonymous attestation of a Trusted Platform Module (TPM) while preserving the privacy …

This paper is motivated by the observation that existing security models for direct
anonymous attestation (DAA) have problems to the extent that insecure protocols may be …
