中文摘要: UC(通用可组合)安全计算的存在性需要刻画某种基础假定的信任模型的支持。针对对于UC安全计算的信任模型研究甚少的现状,从使用信任模型的原因入手,分析比较了国外现有的信任模型,指出了各自的优势和存在的问题。在此基础上,提出了一种公钥基础设施风格的双陷门分离的信任模型DBT模型,作为实验在DBT模型中实现了UC安全的承诺协议。实验结果表明DBT模型集成了现有信任模型的优点,并且支持协议的完全可模拟性。
Abstract:By the analysis of the reason of using a trust model in UC (Universally Composable) secure computation, overseas existing trust models were researched and their merits and demerits were indicated. Then based on Divided Bi-Trapdoor, a trust model named DBT that has the flavor of a “public-key infrastructure” was proposed, and as an experiment, a UC secure commitment protocol was implemented in this model. The DBT model has the complementary benefits of the existing models, and especially supports the full-simulation of protocols.
keywords: cryptographic protocol universally composable secure computation commitment protocol trust model
