基于防篡改硬件模型的UC安全承诺协议
Universally Composable Secure Commitment Protocol Based on Tamper-proof Hardware Model
摘要
Abstract
Beginning with the research of the basic concepts of Universally Composable(UC) framework, the requirement of UC security on commitment protocols is analyzed in this paper, and the reason of the problem that all UC commitment protocols do not exist in the plain model is pointed out that the security requirement of commitment protocol and the requirement of UC security are contradictory. On the basis of this, a UC secure commitment protocol UCCOM using tamper-proof hardware is proposed. Analysis result shows that UCCOM does not depend on any trusted third-party and uses fewer cryptographic operations compared with the related works, so it has higer efficiency.关键词
