A Framework for Universally Composable Oblivious Transfer from One-Round Key-Exchange
Oblivious transfer universal composability key exchange
2019/6/21
Oblivious transfer is one of the main pillars of modern cryptography and plays a major role as a building block for other more complex cryptographic primitives. In this work, we present an efficient a...
One-Round Authenticated Group Key Exchange from Isogenies
one-round authenticated group key exchange cryptographic invariant maps hard homogeneous spaces
2018/11/2
We propose two one-round authenticated group-key exchange protocols from newly employed cryptographic invariant maps (CIMs): one is secure under the quantum random oracle model and the other resists a...
At Indocrypt 2016, Ashur et al. showed that linear hulls are sometimes formed in a single round of a cipher (exemplifying on Simon ciphers) and showed that the success rate of an attack may be influen...
A Pairing-Free, One Round Identity Based Authenticated Key Exchange Protocol Secure Against Memory-Scrapers
Trusted Platform Module identity-based authenticated key exchange
2016/4/7
Security of a key exchange protocol is formally established through an abstract game between a challenger and an adversary. In this game the adversary can get various information which are modeled by ...
One-Round Deniable Key Exchange with Perfect Forward Security
Authenticated Key Exchange Perfect Forward Secrecy Full Deniability
2016/1/7
In response to the need for secure one-round authenticated key exchange protocols providing both perfect
forward secrecy and full deniability, we put forward a new paradigm for constructing protocols...
One-Round Key Exchange with Strong Security: An Efficient and Generic Construction in the Standard Model
One-round key exchange eCK security provable security
2016/1/5
One-round authenticated key exchange (ORKE) is an established research area, with many prominent protocol constructions like HMQV (Krawczyk, CRYPTO 2005) and Naxos (La Macchia et al., ProvSec 2007), a...
Mind the Gap: Modular Machine-checked Proofs of One-Round Key Exchange Protocols
Provable Security Security Protocols EasyCrypt
2016/1/4
Using EasyCrypt, we formalize a new modular security proof for one-round authenticated key exchange protocols in the random oracle model. Our proof improves earlier work by Kudla and Paterson (ASIACRY...
New Techniques for SPHFs and Efficient One-Round PAKE Protocols
Authenticated Key Exchange Blind Signatures Smooth Projective Hash Functions
2016/1/3
Password-authenticated key exchange (PAKE) protocols allow two players to agree on a shared high entropy secret key, that depends on their own passwords only. Following the Gennaro and Lindell's appro...
Strongly Secure One-round Group Authenticated Key Exchange in the Standard Model
cryptographic protocols
2014/3/12
One-round group authenticated key exchange (GAKE) protocols typically provide implicit authentication and appealing bind-width efficiency. As a special case of GAKE -- the pairing-based one-round trip...
New Smooth Projective Hash Functions and One-Round Authenticated Key Exchange
Authenticated Key Exchange Blind Signatures Smooth Projective Hash Functions
2013/2/21
Password-Authenticated Key Exchange (PAKE) has received deep attention in the last few years, with a recent improvement by Katz-Vaikuntanathan, and their one-round protocols: the two players just have...
One-round Strongly Secure Key Exchange with Perfect Forward Secrecy and Deniability
cryptographic protocols / Key Exchange Perfect Forward Secrecy Deniability PKI
2012/3/28
Traditionally, secure one-round key exchange protocols in the PKI setting have either achieved perfect forward secrecy, or forms of deniability, but not both. On the one hand, achieving perfect forwar...

This paper investigates the two-pass authenticated key exchange protocol in the enhanced Canetti-Krawczyk (eCK) with perfect forward security. Currently, there exist no authenticated key exchange prot...
We show a general framework for constructing password-based authenticated key exchange protocols with optimal round complexity --- one message per party, sent simultaneously --- in the standard model,...
