Abstract

Because the PrivacyCA defined in TCG specification may leak user’s privacy and trace his transactions, two PrivacyCA schemes with higher untraceability are proposed. The agents-based one provides higher untraceability by introducing agents and VK certificates to eliminate the linkage between EK and AIK. By adopting Partially Blind Signature algorithm in the generation of AIK triples, PBS-based one provides absolute untraceability to user’s transactions because the public AIK is blinded while being signed by the PrivacyCA. New schemes keep good compatibility to TCG specification and provide different levels of untraceability to satisfy particular applications.
两种具有较高不可追溯性的PrivacyCA方案
由于TCG规范中定义的PrivacyCA可能会泄露用户隐私并跟踪其交易,因此提出了两种具有较高不可追溯性的PrivacyCA方案。基于代理的方式通过引入代理和VK证书来消除EK和AIK之间的链接,从而提供更高的不可追溯性。通过在生成AIK三元组时采用部分盲签名算法,基于pbs的AIK在被PrivacyCA签名时是盲的,因此提供了对用户交易的绝对不可追溯性。新方案与TCG规范保持良好的兼容性,并提供不同级别的不可追溯性以满足特定应用。
