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 Mistyping in Two-Factor-Authenticated Key Exchange
TL;DR: In this paper, Boyen et al. proposed a formal treatment of mistyping in the two-factor authenticated key exchange (KE) setting, which is a natural generalization of Halevi-Krawczyk and Kolesnikov-Rackoff.

TL;DR: Both simulation results and analytical studies reveal that selective alterations of the social network (relations and/or attribute values) according to the proposed protection rule are much more effective than random alterations.

A public key cryptosystem and a signature scheme based on discrete logarithms
TL;DR: A new signature scheme is proposed, together with an implementation of the Diffie-Hellman key distribution scheme that achieves a public key cryptosystem that relies on the difficulty of computing discrete logarithms over finite fields.
