Protocols for deniable authentication achieve seemingly paradoxical guarantees: upon
completion of the protocol the receiver is convinced that the sender authenticated the …

A deniable key exchange allows two parties to jointly share a secret key while neither of two
nor an outsider can prove to a third party that the communication between the two …

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 …

Deniability is defined as a privacy property which enables protocol principals to deny their
involvement after they had taken part in a particular protocol run. Lately, Chou et al. had …

Modeling security for protocols running in the complex network environment of the Internet
can be a daunting task. Ideally, a security model for the Internet should provide the following …

VANETs need secure communication. Authentication in VANETs resists the attack on the
receipt of false information. Authenticated group key agreement (GKA) is used to establish a …

In this paper, we propose a new notion of timed encryption, in which the encryption is secure
within time t while it is completely insecure after some time T> t. We consider the setting …

可否认的群密钥协商协议是指两方或多方参与者在一个开放的公共信道上通过协商得到一个
共享的会话密钥, 并利用该会话密钥建立一个安全的保密信道. 同时, 协议的可否认性使得在协商 …

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 …

This paper describes a secure identity based deniable authentication protocol whose
security is based on difficulty of breaking Diffie-Hellman Problem on Elliptic Curve (ECDHP) …
