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

Off-line Password Guessing Attack on An Efficient Key Agreement Protocol for Secure Authentication
Rongxing Lu,Zhenfu Cao +1 more
TL;DR: It is shown that the proposed protocol cannot resist the off-line password guessing attack and therefore a modified protocol is presented to avoid this attack.

Secure speech biometric templates for user authentication
TL;DR: The authors present two schemes to enhance verification performance in a biometric cryptosystem using a password that can resist a password brute-force search if the biometrics are not compromised.
Strong password-based authentication inTLS using the three-party group Diffie-Hellman protocol
TL;DR: This paper has developed password-based ciphersuites for the Transport Layer Security (TLS) protocol that are not only provably secure but also believed to be free from patent and licensing restrictions based on an analysis of relevant patents in the area.

RhythmLink: securely pairing I/O-constrained devices by tapping
TL;DR: In this article, the authors present a system that improves the wireless pairing user experience by allowing two devices to compare imprecisely-entered tap sequences while maintaining the secrecy of those sequences.

A Formalization of Off-Line Guessing for Security Protocol Analysis
TL;DR: Previous attempts at formalizing off-line guessing consist of extending a Dolev-Yao-style intruder model with inference rules to capture the additional capabilities of the intruder concerning guessable messages but are not fully appropriate for formalizing what off- line guessing precisely means and verifying that a given protocol is not vulnerable to such guessing attacks.

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.

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