Password-encryption is where a client and a server, who share a password, authenticate each other and meanwhile establish a cryptographic key by exchange of messages. In this paper, the authors consider a scenario where two servers cooperate to authenticate a client. Current solutions for dual-server password-encryption are either symmetric in the sense that two peer servers equally contribute to the authentication or asymmetric in the sense that one server authenticates the client with the help of another server. This paper presents a symmetric solution for dual-server password encryption, where the client can establish different cryptographic keys with the two servers, respectively.
