一种新的高效的可否认源认证协议

数据源认证分为可否认的和不可否认的两种.目前,大多数研究都集中在不可否认的数据源认证,可否认的数据源认证相对较少.可否认的数据源认证能够使接收者认证数据的发送源,但却不能向第三方证实数据发送源的真实身份,这种特性对于某些特殊的应用非常重要.概述了几个具有代表性的可否认数据源认证方案,指出主要存在的问题有:交互性,低效性,安全的脆弱性等.提出了一种新的高效安全的可否认源认证协议.

Novel Efficient Deniable Authentication Protocol

Data origin authentication can be classified as deniable authentication and non-deniable authentication.In recent years,many efficient non-deniable authentication protocols have been proposed.However,much less attention is on the deniable authentication.This paper is mainly focused on the research of deniable authentication.A deniable authentication protocol enables a receiver to identify the true source of a given message,but not to prove the identity of the sender to a third party.This property is very im...
