    Efficient Two-Server Password Only Authenticated Key Exchange
   Abstract—
         Password-Authenticated Key Exchange (PAKE) 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 setting, all the passwords
   necessary to authenticate clients are stored in a single server. If the server is
   compromised, due to, for example, hacking or even insider attack, passwords
   stored in the server are all disclosed. In this paper, we consider a scenario where
   two servers cooperate to authenticate a client and if one server is compromised, the
   attacker still cannot pretend to be the client with the information from the
   compromised server. Current solutions for two-server PAKE 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 two-server PAKE,
   where the client can establish different cryptographic keys with the two servers,
   respectively. Our protocol runs in parallel and is more efficient than existing
   symmetric two-server PAKE protocol, and even more efficient that existing
   asymmetric two-server PAKE protocols in terms of parallel computation.

In this setting, all the passwords necessary to authenticate clients are stored in a single server. If the server is compromised, due to, for example, hacking or even insider attack, passwords stored in the server are all disclosed.

Current solutions for two-server PAKE 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 two-server PAKE, where the client can establish different cryptographic keys with the two servers, respectively. Our protocol runs in parallel and is more efficient than existing symmetric two-server PAKE protocol, and even more efficient that existing asymmetric two-server PAKE protocols in terms of parallel computation.
