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

No-Match Attacks and Robust Partnering Definitions: Defining Trivial Attacks for Security Protocols is Not Trivial
Yong Li,Sven Schäge +1 more
TL;DR: This work introduces no-match attacks, a new class of attacks that renders many existing security proofs invalid and provides a conceptually new definition of partnering that circumvents the problems of a MC-based partnering notion while preserving all its advantages.
