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

Strongly Password-Based Three-Party Authenticated Key Exchange Protocol
TL;DR: This paper proposes a strongly password-based three-party authenticated key exchange protocol based on the Diffie-Hellman key exchange idea and a one-way hash function, and shows the proposed protocol is secure and it can meet a series of security attributes.

Delayed password disclosure
Markus Jakobsson,Steven Myers +1 more
TL;DR: A new authentication protocol called Delayed Password Disclosure is presented, aimed at reducing the effectiveness of phishing/spoofing attacks that are becoming increasingly problematic for Internet users by providing the user with dynamic feedback while password entry occurs.

Towards Isogeny-Based Password-Authenticated Key Establishment
TL;DR: This work proposes the first quantum-resistant password-authenticated key exchange scheme based on supersingular elliptic curve isogenies, which uses the password to generate permutations which obscure the auxiliary points.
