Encrypted key exchange: password-based protocols secure against dictionary attacks

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. >

Authenticated Key Exchange Protocol Secure against Offline Dictionary Attack and Server Compromise

TL;DR: This paper introduces a new scheme, called Augmented Password AKE (APAKE), for authenticated key exchange protocols, where a password is represented by a pair of values that is randomly selected in a huge space.

What are multi-protocol guessing attacks and how to prevent them

TL;DR: A systematic procedure to analyze protocols subject to guessing attacks is developed and this procedure is used to derive some syntactic conditions to be followed, in order for a protocol to be secure against multi-protocol guessing attacks.

Post-Quantum Secure Remote Password Protocol from RLWE Problem

TL;DR: A RLWE-based SRP protocol (RLWE-SRP) which inherit advantages from SRP and elegant design from RLWE key exchange is proposed which is more than 3x faster than 112-bit secure originalSRP protocol, 5.5X faster than 80-bitSecure J-PAKE and 14x faster Than two 184-bit Secure RLWE -based PAKE protocols with more desired properties.

On the Provable Security of the Dragonfly Protocol

TL;DR: This paper proves the security of a very close variant of Dragonfly in the random oracle model, which shows in particular that Dragonfly's main flows - a kind of Diffie-Hellman variation with a password-derived base - are sound.

A public key cryptosystem and a signature scheme based on discrete logarithms

TL;DR: A new signature scheme is proposed, together with an implementation of the Diffie-Hellman key distribution scheme that achieves a public key cryptosystem that relies on the difficulty of computing discrete logarithms over finite fields.

A Public Key Cryptosystem and a Signature Scheme Based on Discrete Logarithms

TL;DR: In this article, a new signature scheme is proposed together with an implementation of the Diffie-Hellman key distribution scheme that achieves a public key cryptosystem and the security of both systems relies on the difficulty of computing discrete logarithms over finite fields.
