Information Coordination Protocol Based On (15,5,7) BCH Codes

With the rapid development of computer technology and communication technolo-gy, people have higher requirement about the information. The society has entered into the information age. At the same time,the security of information transmission has at-tracted more and more attention. The cryptosystem which is based on the computational complexity is facing a challenge. As a branch of cryptography, quantum cryptography has great application in protecting information and the security protection of the information.According to modern cryptography, the security of the encryption system is decid-ed by the private level of the key. Encryption and decryption algorithms in encryption system can be made known to public, so the effective management of the key and the key in cryptography and communication security plays an important role. Currently, the quantum key distribution is the most mature in quantum key management theory and technology. This article focuses on quantum key distribution information application by error correction technology. The main work in this article is as follows:(1) Analyze the decoding algorithms of BCH code and put forward the BCH code sim-plified table lookup decoding algorithm, pointing out the advantages of using the algorithm to information reconciliation.(2) Introduce a known information reconciliation protocol based on BCH code and point out the theoretical errors of this information reconciliation. And presents a specific example verification.(3) Based on the BCH code which is combined with a simplified table lookup decoding algorithm:an information reconciliation protocol based on (15,5,7) BCH code is put forward. And the proposed protocol is simulated. Through the analysis of experimental data, it shows that the protocol has certain feasibility.
