可否认认证不仅可以像数字签名那样实现消息认证,且非公开可验证性使其可以满足许多签名不能满足的需求,如隐私保护等。研究了如何在多方协议中实现完全可否认认证,利用承诺方案提出了一个适用于多方协议的可否认认证。该方案作为一种一般化的方法,能够为大多数多方协议实现可否认认证,如可否认的群密钥协商协议等,形式化了方案的敌手模型并严格证明了方案的安全性,为研究可否认认证提供了一种新思路。
Deniable authentication can authenticate messages like digital signatures
and its non-public verification can meet many requirements that cannot be met by signatures
such as privacy preservation.How to achieve deni-able authentication with multi-party protocol was the study aim.A deniable authentication for multi-party protocol using string commitment scheme was proposed.As a generic method
it can pass the most of protocol to deniable protocol
such as the deniable group key agreement protocol.The adversarial model was formalized and the security was proved strictly.The research content provide a new idea for studying deniable authentication.
