Cryptanalysis of a Classical Chaos-Based Cryptosystem with Some Quantum Cryptography Features
David Arroyo, Fernando Hernandez, Amalia Beatriz Orue · International Journal of Bifurcation and Chaos · 2017
The application of synchronization theory to build new cryptosystems has been a hot topic during the last two decades. In this paper, we analyze a recent proposal in this field. We pinpoint the main limitations of the software implementation of chaos-based systems designed on the grounds of synchronization theory. In addition, we show that the cryptosystem under evaluation possesses serious security problems that imply a clear reduction of the key space.
