Cubic Quantum Security

Quantum cryptography provides us new methods of securing the communications. As compared to classical cryptography, which implies different mathematical algorithms to secure the information, quantum cryptography focuses on the physical support of the information. The process of information transmission or stocking is realized by the intermediation of a physical support, for example the photons transmitted by optical fiber or the electrons from the electricity. Communication security can be regarded as securing the physical support of the carrier of the information - in our case the photons from the optical fiber. Consequently, how and what an attacker can find out depends exclusively on the laws of physics. The paper presents a symmetrical encryption method based on the method of mixture used by the rubik´s cube.
