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

Secure cross-realm client-to-client password-based authenticated key exchange against undetectable on-line dictionary attacks
TL;DR: A new cross-realm C2C-PAKE scheme with the optimal number of rounds for a client is proposed, which has resistances to previously considered attacks which should be prevented, including undetectable on-line dictionary attacks and unknown-key share attacks.

TL;DR: It is shown that not only are Halevi and Krawczyk's PAKE protocols vulnerable to ephemeral key compromise impersonation and malicious server attacks, but they also fail to provide key confirmation property simultaneously, one of which does not even satisfy Forward Secrecy attribute.
