摘要
为了有效实现矿用高压电网继电保护定值的安全传输,提出了基于量子纠缠和信道自校验的定值传输协议,该协议基于量子纠缠特性实现定值数据的安全传输, 并在该协议中引入了信道自校验功能。在完成定值可靠传输的基础上进一步减少了量子纠缠对的消耗,建立了完成数据传输所需纠缠数与所经过的路由器数量和 分组传输错误率之间的定量关系,并与基于量子纠缠信道的定值传输协议进行了比较。仿真结果表明,与基于量子纠缠信道的定值传输协议相比, 无论量子通信网络是否稳定,基于量子纠缠和信道自校验的定值传输协议只需要消耗较少的纠缠粒子对就能够完成继电保护定值的安全传输; 当量子通信网规模增大时,所提协议需要消耗的纠缠粒子对数量较少,适用于较大规模的量子通信网。
Abstract
In order to achieve the safe transmission of protection setting in the coalmine high-voltage power grid, a protection setting transmission protocol based on quantum entanglement and channel self-checking is proposed. The protocol realizes the secure transmission of protection setting based on quantum entanglement properties, and consumes the less entangled particles by introducing the channel self-checking function. It establishes the quantitative relation between the consumed entangled particles number, number of routers that passes through and the transmission error rate of the packet. The simulation results show that compared with the setting transmission protocol based on quantum entanglement channel, it can complete the secure transmission of protection setting by consuming less entangled particles, whether the quantum communication network is stable or not. And when the quantum communication network scale increases, the proposed protocol consumes less entangled particles in transmission process, and it is more suitable for large-scale quantum communication network.
