Direct anonymous attestation on the road [PDF]
Proceedings of the 14th ACM Conference on Security and Privacy in Wireless and Mobile Networks, 2021 Vehicular networks rely on Public Key Infrastructure (PKIs) to generate long-term and short-term pseudonyms that protect vehicle’s privacy. Instead of relying on a complex and centralized ecosystem of PKI entities, a more scalable solution is to rely on Direct Anonymous Attestation (DAA) and the use of Trusted Computing elements.

Direct Anonymous Attestation with Efficient Verifier-Local Revocation for Subscription System [PDF]
Proceedings of the 2018 on Asia Conference on Computer and Communications Security, 2018 For a computing platform that is compliant with the Trusted Platform Module (TPM) standard, direct anonymous attestation (DAA) is an appropriate cryptographic protocol for realizing an anonymous subscription system. This approach takes advantage of a cryptographic key that is securely embedded in the platform's hardware, and enables privacy-preserving ...
