摘　　要：为提高高压电网用户信息传输的带宽,减少信息传输的拥堵现象,提出基于改进DES的高压电网用户信息安全传输方法。利用改进DES加密算法对高压电网用户信息进行加密,并利用区域推进机制将加密后的数据推进到节点中,以此确保节点的均衡能耗,通过节点对数据包进行传输及接收,实现用户信息安全传输。实验结果表明,该方法在不同节点运动速度下,数据传输带宽下降速度慢,数据传输拥堵次数少,表明该方法的传输效果强,具有较高的实用性。In order to improve the bandwidth of user information transmission in high-voltage power grid and reduce the congestion of infor-mation transmission,a safe transmission method of user information in high-voltage power grid based on improved DES is pro-posed.The improved DES encryption algorithm is used to encrypt the user information of the high-voltage power grid,and the en-crypted data is pushed to the nodes by the regional push mechanism,so as to ensure the balanced energy consumption of the nodes,and the data packets are transmitted and received by the nodes to realize the safe transmission of user information.The ex-perimental results show that the data transmission bandwidth decreases slowly and the data transmission congestion times are less under different node movement speeds,which indicates that the method has strong transmission effect and high practicability.
