摘要
为了提高物联网通信信道的通信效率和安全性,对物联网通信信道的量子密钥协议进行研究,分析了基于BB84协议的量子密钥分配系统以及通信原理,在量子密钥协议中融入筛选数据、数据纠错以及身份认证过程,增强物联网通信信道内光子通信的质量。面向物联网通信信道的多样性和复杂性,提出基于BB84的多用户量子密钥分发协议,确保物联网各通信终端基于最高的概率得到一致的密钥。采用4维Hilbert空间上的量子密钥分配协议,将BB84协议中二维Hilbert空间中的单个量子的密钥协商发展到4维Hilbert空间中,提高物联网通信信道的通信效率。实验结果说明,所提量子密钥协议,提高了物联网通信信道的通信效率和安全性。
In order to improve the communication efficiency and security of the Internet communication channel, the Internet communication channel of quantum key agreement is studied, based on the BB84 protocol of quantum key distribution system are analyzed and the principle of communication, in the quantum key agreement into the screening data, the data error correction and authentication process, increase the quality of iot photon communication within a communication channel. Geared to the needs of the diversity and complexity of Internet communications channel, based on multi-user quantum key distribution protocol of BB84 and ensure that the Internet of things the communication terminal based on the highest probability to get consistent key. Using 4 d quantum key distribution protocol on the Hilbert space, the BB84 protocol in two-dimensional single quantum key agreement in the Hilbert space development to 4 d in the Hilbert space, improve the communication efficiency of Internet communication channel. Experimental results indicate that the proposed quantum key agreement, improve the communication efficiency and security of the Internet communication channel.
