A Chaotic Quantum Secure Communication Scheme Based on a Mixed Open System

A system of a particle kicked by aGaussian beam is studied. A description of the chaoticbehavior of this system is presented. The suitability of themodel for cryptography is demonstrated by applying theEinstein-Podolsky-Rosen correlations and calculating theentanglement parameter. Based on this model, we introducea quantum secure communication protocol. By using theShannon information theory about the detailed analysis of theGaussian cloner attack strategy about this system, wedemonstrate that the system is both safe and reliable. Theresults show that the proposed algorithm improves theproblem of failure of encryption, such as small key space andlevel of security.
