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

Three-party encrypted key exchange: attacks and a solution
TL;DR: This paper shows a new off-line guessing attack on Steiner, Tsudik and Waidners' protocol and proposes a new three-party EKE protocol which not only is secure against both the off-lines guessing attack and undetectable on-line guesses but also satisfies the security properties of perfect forward secrecy and known-key security.

Towards a completeness result for model checking of security protocols
TL;DR: The author presents sufficient conditions on the protocol and its environment such that if there is no attack upon a particular small system leading to a breach of secrecy (using a fairly strong definition of secrecy), then there will be no attack on any larger system lead to a breaches of secrecy.

Pass-thoughts: authenticating with our minds
TL;DR: The motivation and potential of pass-thought authentication, the status quo of BCI technology, and the design of what the authors believe to be a currently feasible pass- Thought authentication system are discussed.

Session-Key Generation Using Human Passwords Only
Oded Goldreich,Yehuda Lindell +1 more
TL;DR: In this paper, the authors present session-key generation protocols in a model where the legitimate parties share only a human-memorizable password, and there is no additional set-up assumption in the network.

New Security Results on Encrypted Key Exchange
TL;DR: AuthA was shown to be secure under the assumption that the hash function closely behaves like a random oracle and that the computational Diffie-Hellman problem is difficult.

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.
