摘要
跨域客户到客户基于口令认证的密钥交换(C2C-PAKE)协议具有重要的应用价值。但是,目前的大部分C2C-PAKE协议都无法抵抗口令泄露攻击。该文给出了一个新的跨域客户到客户的口令认证密钥交换协议。该协议带有签名体制且交互次数较少。随后,在一般模型下对给出的协议进行了安全性证明。该协议可以抵抗口令泄露等各种攻击,并且具有前向安全性质。
Cross-realm client-to-client password-authenticated key exchange(C2C-PAKE) protocols are important in web communication.But most C2C-PAKE protocols can not resist password-compromise impersonation attack.This paper provides a new cross-realm C2C-PAKE protocol with signature scheme and low communication cost.Then the security of the protocal is proved under general model.The new protocol can be resistant to many attacks such as password-compromise impersonation attack and so on.Furthermore,this protocol provides the property of the perfect forward secrecy.
