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

Security analysis and enhancement for three-party password-based authenticated key exchange protocol
Jianjie Zhao,Dawu Gu,Lei Zhang +2 more
TL;DR: It is found that the leakage of values VA and VB in the CLC protocol will make a man-in-the-middle attack feasible in practice, and on the basis of this finding, a modified 3PAKE protocol called I-CLC protocol is presented, which is essentially an improved C LC protocol.

An enhanced password authenticated key exchange protocol without server public keys
TL;DR: It is shown that the DH-BPAke protocol is vulnerable to password compromise impersonation attack and it is not efficient due to the number of running steps and its computational load, and an enhanced PAKE protocol is proposed which provides several security properties.
