TLDR
A combination of asymmetric (public-key) and symmetric (secret- key) cryptography that allow two parties sharing a common password to exchange confidential and authenticated information over an insecure network is introduced.Abstract:
Classic cryptographic protocols based on user-chosen keys allow an attacker to mount password-guessing attacks. A combination of asymmetric (public-key) and symmetric (secret-key) cryptography that allow two parties sharing a common password to exchange confidential and authenticated information over an insecure network is introduced. In particular, a protocol relying on the counter-intuitive motion of using a secret key to encrypt a public key is presented. Such protocols are secure against active attacks, and have the property that the password is protected against offline dictionary attacks. >read more

TL;DR: A compiler is presented that transforms any group key exchange (KE) protocol which is secure against a passive eavesdropping to a group PAKE which isSecure against an active adversary who controls all communications in the network.
An EAP Authentication Method Based on the Encrypted Key Exchange (EKE) Protocol
TL;DR: This document defines an authentication mechanism for EAP called EAP-EKE, based on the Encrypted Key Exchange (EKE) protocol, which provides mutual authentication through the use of a short, easy to remember password.

TL;DR: In this article, the authors consider the security of the n-party EKE-U and eKE-M protocols proposed by Byun and Lee at ACNS '05 and show that both of them are vulnerable to impersonation attacks, offline dictionary attacks and undetectable online dictionary attacks.

Cryptanalysis of a Three-Party Authenticated Key Exchange Protocol Using Elliptic Curve Cryptography
TL;DR: It is demonstrated that Yang et al's three-party authenticated protocol is potentially vulnerable to an unknown key-share attack, and a countermeasure is suggested to resist attacks while the merits of the original protocol are left unchanged.

On robust key agreement based on public key authentication
TL;DR: This paper critically analyze several authenticated key agreement protocols and uncover various theoretical and practical flaws and presents two new attacks on the Hashed Menezes-Qu-Vanstone HMQV protocol, which is currently being standardized by IEEE P1363.
