摘　　要：为满足在电子商务和电子政务等领域中的应用要求,深入分析和研究了非交互式可否认认证协议的理论和相关应用。根据不同的应用环境,将可否认认证协议分为交互式和非交互式两类,并分析了这两种类别协议的通信轮数的开销,指出在电子投票和电子邮件协商等应用中需要非交互式的可否认认证这一结论。最后,在对几个典型的非交互式可否认认证协议分析的基础上,指出现有的成果不能满足应用的需要,探讨了在非交互式可否认认证领域的研究方向。To satisfy the application requirement in electronic commence and electronic government field,the characteristic and the application of non-interactive deniable authentication protocols are intensively researched.According to the various applications,the deniable authentication protocols are divided into interactive protocols and non-interactive protocols.The cost of the communication rounds about the two types of protocols are analyzed and the fact that electronic voting and E-mail negotiation need non-interactive protocols is proposed.Finally,based on the analysis of some typical non-interactive protocols,the fact that the present researches cannot satisfy the needs of applications is pointed out,and the future research aspects about non-interactive deniable authentication are discussed.
