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

Provably Secure Password-based Authentication in TLS
TL;DR: The Simple Open Key Exchange (SOKE) as mentioned in this paper is a password-based authenticated key exchange scheme for the TLS (Transport Layer Security) protocol that allows users to employ (short) passwords to securely identify themselves to servers.

Password-Based Authentication: Preventing Dictionary Attacks
Saikat Chakrabarti,M. Singbal +1 more
TL;DR: Password-based authentication is susceptible to attack if used on insecure communication channels like the Internet, so formal models to analyze and aid in the effective design of acceptable password protocols geared to prevent dictionary attacks are needed.

Password-Based authenticated key exchange
TL;DR: Authenticated Key Exchange protocols enable several parties to establish a shared cryptographically strong key over an insecure network using various authentication means, such as strong cryptographic keys or short (i.e. low-entropy) common secrets.
Anonymity and one-way authentication in key exchange protocols
TL;DR: In this paper, the authors proposed a key exchange protocol that provides one-way authentication and anonymity in the setting of private shared session keys, where only one party authenticates to the other.

On session identifiers in provably secure protocols: the Bellare-Rogaway three-party key distribution protocol revisited
TL;DR: There seems to be no way to define a SID for the 3PKD protocol that will preserve the proof of security, so a small change to the protocol allows a natural definition and it is proved that the new protocol is secure using this SID to define partnering.

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.

A Public Key Cryptosystem and a Signature Scheme Based on Discrete Logarithms
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.
