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

New Techniques for SPHFs and Efficient One-Round PAKE Protocols
TL;DR: The first concrete one-round password-authenticated key exchange (PAKE) protocol was proposed by Katz and Vaikuntanathan as discussed by the authors, where two players agree on a shared high entropy secret key, that depends on their own passwords only.
