ABSTRACT

In order to give a unified theoretical basis for modern cryptography and various quantum cryptography protocols, we must redefine cryptography in Hilbert space. One of the core contents of modern cryptography is public key cryptography. Therefore, it is a basic task to construct a public key cryptography system for quantum message, and to establish a unified theory covering classical public key cryptosystem and quantum public key cryptosystem. This project is to study the public key cryptography for quantum news, that is, the quantum message is the object of protection, based on quantum message space, quantum key space and quantum cryptography algorithm. Based on quantum information theory and quantum computing complexity theory, Quantum Public Key Cryptography Applied to Quantum Computing Environment. In view of the fact that the quantum information theory has been established for 40 years, the theory of quantum computing complexity based on quantum graphs and quantum circuits has begun to take shape. The research plan has a good theoretical starting point. This paper focuses on the new nature and new rules of quantum key cryptography, which is different from the new public key cryptography algorithm. It is devoted to the establishment of the theoretical framework of quantum cryptography and explore the framework of classical public key cryptography and quantum key cryptography Unified theory. Hope that the work of this project can also help the classic cryptographer to explore the classic public key cryptography new development path. More... »
