Abstract: Existing password authenticated key exchange (PAKE) protocols have been found to be unsafe, vulnerable to dictionary attack and server compromise attack. This paper analyzed the reason of the key authentication protocol suffering from server compromise attack and proposed a new PAKE protocol. This protocol with a total of six steps can against dictionary attack and server compromise attack, and also provide forward security.
Key words: data security and computer security; password-authentication; key exchange; dictionary attack; server compromise attack; forward security
