Cryptanalysis of a Classical chaos-based cryptosystem with some quantum cryptography features
This work highlights vulnerabilities in a specific cryptosystem, which is incremental as it critiques an existing proposal without introducing new solutions.
The paper analyzes a recent chaos-based cryptosystem, identifying key limitations in its software implementation and serious security problems that significantly reduce the key space.
The application of synchronization theory to build up 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.
