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

Public-key encryption indistinguishable under plaintext-checkable attacks
TL;DR: The authors design a new public-key encryption scheme satisfying indistinguishability under plaintext-checking attacks (IND-PCA), and show that, for many password-based authenticated key exchange (PAKE) schemes in the Bellare–Pointcheval–Rogaway security model, they can safely replace the underlying IND-CCA encryption schemes with their new IND- PCA one.

Security Analysis of a Password Authenticated Key Exchange Protocol
TL;DR: In this article, a security analysis of the RSA-based password authenticated key exchange (PAKE) protocol is presented, and it is shown that the protocol is vulnerable to dictionary attack when the length of the ID of the second party is small.
