给定仲裁器的仲裁是可信的，认证方案是无条件安全的模仿和/或替换攻击的仲裁器执行，而以前的计划并没有防止这种攻击。此外，该方案无条件地防止：模仿/替代攻击由外人完成，对否认的消息由发送者，并对接收者伪造的消息，这是从来没有发送。提出了一种基于有限几何的实用方案。该方案的改进实现了一个非对称的传统认证方案，并建立了一个无条件安全的不经意传输系统。
Given an arbiter whose arbitrage is trusted, an authentication scheme is presented which is unconditionally secure against impersonation and/or substitution attacks performed by the arbiter, whereas previous scheme did not protect against such attacks. Furthermore, the scheme protects unconditionally against: impersonation/substitution attacks done by an outsider, against disavowal of a message by the sender, and against the receiver forging a message which was never sent. A practical scheme based on finite geometry is presented. Adaptations of the scheme realize an asymmetric conventional authentication scheme, and the set-up of an unconditionally secure oblivious transfer system.
