An Anonymous Attestation Scheme in Inter-domain Environment with Enhanced Security

In this paper, we point out the deficiencies of the existing DAA schemes on member revocation, inter-domain attestation and Rudolph´s attack prevention and present a new scheme called Enhanced Privacy Inter-domain Anonymity Attestation based on Peer-to-Peer Networks. We add a new party called Trusted Auditor (TA) and construct a TA level above the existing DAA scheme. Analysis shows that the proposed model is feasible and that not only the security of the model is enhanced, but also inter-domain attestation is facilitated. Simulation results show that the scheme makes great improvement in member revocation and other security issues.
