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

Preserving user-participation for insecure network communications with CAPTCHA and visual secret sharing technique

TL;DR: This study aims to develop a robust system that can guarantee the user-participation essential in the communication, and if the involved participants cannot prove that they are human beings, then the system will terminate the connection to prevent the attack.

Pass-thoughts: Authenticating With Our Minds.
TL;DR: Pass-thoughts as discussed by the authors is an idea for user authentication that extracts as much entropy as possible from a user's brain signals upon "transmitting" a thought, provided that these brain signals can be recorded and processed in an accurate and repeatable way, providing a quasi-two-factor, changeable, authentication method resilient to shoulder-surfing.
