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

Provably secure three-party password-based authenticated key exchange protocol

TL;DR: This paper proposes a 3PAKE protocol which is provably secure if the Diffie-Hellman problem is computationally infeasible (the CDH assumption), even in the 3eCK model where the adversary is allowed to make more queries and have more freedom than previous models.

An attack on the Interlock Protocol when used for authentication
S.M. Bellovin,M. Merritt +1 more
TL;DR: The authors demonstrate that an active attacker can, at the cost of a timeout alarm, bypass the passwork exchange, and capture the passwords used.

Analysis of the SPEKE password-authenticated key exchange protocol
TL;DR: This analysis contradicts the claim that the SPEKE protocol appears to be at least as strong as the Bellovin-Merritt EKE protocol, and shows that a fully-constrained SPEke is susceptible to password guessing attack.
