The invention discloses a security protection method for internal communication information of a charging pile, which comprises the following steps: a trusted device A generates and stores a key A, and a device B generates and stores a key B which is the same as the key A; the device A'sends a handshake request to the device B, wherein the handshake request comprises a handshake request packet, request time, request time and a first hash value of the key A '; after receiving the handshake request, the device B calculates a second hash value based on the request time and the key B; comparing the first hash value with the second hash value, if the first hash value is consistent with the second hash value, indicating that handshake succeeds, and allowing communication; otherwise, handshake fails, and communication is not allowed. According to the method, the credibility and the security of the access equipment in the communication network can be ensured, the security problems of electricity utilization risk and the like caused by electricity stealing and malicious data forgery are avoided, and the can communication data are prevented from being intercepted, analyzed and tampered.

    本发明公开了一种充电桩内部通讯信息的安全防护方法,包括:可信任设备A生成并保存密钥A,设备B生成并保存与密钥A相同的密钥B;设备A’向设备B发送握手请求,握手请求包括:握手请求包、请求时间、请求时间和密钥A’的第一hash值;设备B接收握手请求后,基于请求时间和密钥B,计算第二hash值;比较第一hash值与第二hash值,若一致,则握手成功,允许通信;否则,握手失败,不允许通信。本发明可以确保通讯网络中接入设备的可信任性和安全性,避免出现窃电,恶意伪造数据导致的用电风险等安全问题,防止can通讯数据被拦截解析,篡改。
