Abstract:Klein et al. proposed a key exchange protocol using chaos synchronization. The first protocol comprises two parties with chaotic dynamics that are mutually coupled and undergo a synchronization process, at the end of which they can use their identical dynamical state as an encryption key. From cryptographic point of view, their key exchange protocol is a key agreement protocol. Klein et al. claimed that their key agreement can be
carried out over a public channel. In order to increase the key space and decrease the precision of the calculation, they made an
extension of the system to a network of N Lorenz equations. In this paper, we will provide a cryptanalysis of their key agreement
protocol. We will first point out some weaknesses, and then show that their protocol is not secure against several attacks including
impersonation attack. © 2007 Elsevier Ltd. All rights reserved.
