Bilinear Pairing Based DAA Protocol
Hong-hu Zhen, Yue Chen · 2009
Direct anonymous attestation (DAA) is adopted by the trusted platform module (TPM) of v1.2 standard described by the trusted computing group (TCG), aimed at settling protocols for trusted platform attestation and platform privacy protection. This paper gives a presentation of the new DAA protocol based on bilinear pairings and an analysis of its capacity to realize both attestation anonymity and detection of malicious attacks. Comparing with the existing three kinds of DAA protocols (the initial one, the improved one and the one based on oblivious transfer), this new protocol is of the simplest but also the most efficient.
