Group key-exchange protocols allow a set of N parties to agree on a shared, secret key by communicating over a public network. A number of solutions to this problem have been proposed over the years, ...
One-Round Authenticated Group Key Exchange from Isogenies

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...
We design a group key exchange protocol where most of the participants remain offline until they wish to compute the key. This is well suited to a cloud storage environment where users are often offli...

When a group key exchange protocol is executed, the session key is typically extracted from two types of secrets;
long-term keys (for authentication) and freshly generated (often random) values. The ...

Minimizing complexity of group key exchange (GKE) protocols is an important milestone
towards their practical deployment. An interesting approach to achieve this goal is to simplify the
design of GK...

We treat the security of group key exchange (GKE) in the universal composability (UC)
framework. Analyzing GKE protocols in the UC framework naturally addresses attacks by malicious
insiders. We def...

A key exchange protocol allows a set of parties to agree upon a secret session key over a
public network. Two-party key exchange (2PKE) protocols have been rigorously analyzed under various
models c...

We consider the fundamental problem of authenticated group key exchange among
n parties within a larger and insecure public network. A number of solutions to this
problem have been proposed; however...

Group key agreement protocols are designed to solve the fundamental problem of securely
establishing a session key among a group of parties communicating over a public channel.
Although a number of ...

In this paper we propose two compilers which are designed to transform a
group key exchange protocol secure against any passive adversary into an
authenticated group key exchange protocol with key c...

Protocols for authenticated key exchange (AKE) allow parties within an insecure network to
establish a common session key which can then be used to secure their future communication.
