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 in-band wireless pairing
TL;DR: The main innovation is a new key exchange message constructed in a manner that ensures an adversary can neither hide the fact that a message was transmitted, nor alter its payload without being detected, which translates into the pairing devices detecting either invalid pairing messages or an unacceptable increase in the number of such messages.

Elliptic Curve Based Password Authenticated Key Exchange Protocols
TL;DR: It is shown that the direct elliptic curve (EC) analogs of some PAKE protocols are insecure against partition attacks and a new EC based PAKE protocol is proposed.
