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

Password authenticated key exchange by juggling
Feng Hao,Peter Y. A. Ryan +1 more
TL;DR: J-PAKE as mentioned in this paper is a password-authenticated key exchange by juggling (PAKE-J) protocol, which achieves mutual authentication in two steps: first, two parties send ephemeral public keys to each other; second, they encrypt the shared password by juggling the public keys in a verifiable way.
