短群签名在可信计算中的应用研究

远程证明提供了平台身份匿名认证功能，并给出了基于隐私CA及直接匿名认证两种方案。直接匿名认证方案的提出意在解决隐私CA方案中的CA瓶颈问题。文章提出了一种全新的直接匿名认证方案：以标准模型下的短群签名机制为主线，以1-MOMSDH假设为安全基础，在与现有方案保持相似效率的前提下，提高协议整体安全性。

Short Group Signature in Trusted Computing

Remote attestation realizes the platform identity authentication anonymously through Privacy CA and Direct Anonymous Attestation .DAA solves the bottleneck problem from the Privacy CA.This paper proposes a new DAA protocol from short group signature which takes the short group signatuse in standard models as main line,and the 1 MOMSDH assumption as security fundation.It improves the whole security of DAA and maintains the same efficiency.
