Research of Platform Anonymous Identity Management Based on Trusted Chip
Yu Ai · Chinese Journal of Computers · 2010
TPM/TCM-Based platform identity management is the base to construct TNC(trusted network connect).However there are two problems when managing platform identity of the network terminals using privacy-CA and DAA(direct anonymous attestation)approaches.The first one is that it is hard to manage EK certificate of TPM/TCM,especially in large scale networks.Secondly traditional administrator-based terminal management can not be combined with the approaches based on TPM/TCM.The paper proposes an improved approach to manage terminal platform identity based on TPM/TCM.It defines the protocols to issue EK,establish platform anonymous identity,revoke platform identity,and authenticate platform identity.Moreover the security of this approach is proven under RO(random oracle)model.
