Security of EPR-based Quantum Cryptography

Abstract

Quantum cryptography based on quantum physics has been proved to be an effective means of key security allocation in secure communication. This paper introduces you to the basic principle of quantum cryptography on the basis of classical cryptography, and then presents several methods of quantum cryptography. It expounds the main research on EPR key distribution mechanism based on entanglement, according to quantum cryptography communication history and the existing problems. Lastly the advanced prospect and research aspect were predicted.
