Quantum Diffie–Hellman key exchange

open access: yesAPL Quantum
The Diffie–Hellman key exchange plays a crucial role in conventional cryptography, as it allows two legitimate users to establish a common, usually ephemeral, secret key.

The Group Diffie-Hellman Problems [PDF]

open access: yes, 2003
In this paper we study generalizations of the Diffie-Hellman problems recently used to construct cryptographic schemes for practical purposes. The Group Computational and the Group Decisional Diffie-Hellman assumptions not only enable one to construct efficient pseudo-random functions but also to naturally extend the Diffie-Hellman protocol to allow ...

Separating Decision Diffie-Hellman from Diffie-Hellman in cryptographic groups.

open access: yesIACR Cryptol. ePrint Arch., 2001
In many cases, the security of a cryptographic scheme based on Diffie--Hellman does in fact rely on the hardness of the Diffie--Hellman Decision problem.

On The Diffie-Hellman Assumption.

open access: yesIACR Cryptol. ePrint Arch., 2008
We generalize the Strong Boneh-Boyen (SBB) signature scheme to sign vectors (GSBB). We show that if a particular (but most natural) average case reduction from SBB to GSBB exists, then the Strong Diffie-Hellman (SDH) and the Computational Diffie-Hellman (

On the index of the Diffie–Hellman mapping [PDF]

open access: yesApplicable Algebra in Engineering, Communication and Computing, 2020
In this paper, the authors determine the index of the univariate Diffie-Hellman mapping \(d(\gamma^a) = \gamma^{a^2}\), \(0 \le a \le n-1\), and \(\gamma\) is a generator of a cyclic group \(G\) of order \(n\). They show that any mapping of small index coincides with \(d\) only on a small subset of \(G\).

Easy Decision Diffie-Hellman Groups [PDF]

open access: yesLMS Journal of Computation and Mathematics, 2004
AbstractThe decision Diffie-Hellman problem (DDH) is a central computational problem in cryptography. It is known that the Weil and Tate pairings can be used to solve many DDH problems on elliptic curves. Distortion maps are an important tool for solving DDH problems using pairings, and it is known that distortion maps exist for all super-singular ...

Diffie-Hellman Oracles [PDF]

open access: yes, 1996
This paper consists of three parts. First, various types of Diffie-Hellman oracles for a cyclic group G and subgroups of G are defined and their equivalence is proved. In particular, the security of using a subgroup of G instead of G in the Diffie-Hellman protocol is investigated.
