Design and analysis of group key exchange protocols [PDF]
, 2010 A group key exchange (GKE) protocol allows a set of parties to agree upon a common secret session key over a public network. In this thesis, we focus on designing efficient GKE protocols using public key techniques and appropriately revising security ...

An active attack on a distributed Group Key Exchange system
, 2016 In this work, we introduce an active attack on a Group Key Exchange protocol by Burmester and Desmedt. The attacker obtains a copy of the shared key, which is created in a collaborative manner with the legal users in a communication ...

Non-invertible key exchange protocol
SN Applied Sciences, 2020 We investigate a cryptosystem through what we call non-invertible cryptography. As a result of a continuous refinement process, we present a new key exchange method to establish a secret key between two remote parties.

Proposal to Complex DES Security Using Diffie Hellman Injection [PDF]
Engineering and Technology Journal, 2011 Data Encryption Standard (DES) is based on a round of starters, from the results of the use of multi-stage permutation and replacement to the more complex algorithm which adopts the symmetric key.

EasyUC: using EasyCrypt to mechanize proofs of universally composable security [PDF]
, 2019 We present a methodology for using the EasyCrypt proof assistant (originally designed for mechanizing the generation of proofs of game-based security of cryptographic schemes and protocols) to mechanize proofs of security of cryptographic protocols ...

A new key exchange protocol based on the decomposition problem [PDF]
, 2005 In this paper we present a new key establishment protocol based on the decomposition problem in non-commutative groups which is: given two elements $w, w_1$ of the platform group $G$ and two subgroups $A, B \subseteq G$ (not necessarily distinct), find ...
