摘　　要：传统加密方法节点破解率较高,安全性不佳,提出基于透明加密的低压输电网络安全传输敏感数据加密控制技术。通过同态加密将感知请求发送至与输电网络基站距离最小的根节点,并将所接收的感知命令传送至下级子节点;通过预设处理同态加密密钥池形成随机密钥,利用索引值理论生成同态密文实现敏感数据加密控制;引入透明加密结合分段Logistics混沌排列透明加密敏感数据,构建网络安全传输敏感数据加密认证协议,实现数据加密控制。实验结果表明,改进方法可保障较低节点破解率,信息可读性高于99%,可保护用户隐私数据安全性。Traditional encryption methods have high node cracking rate and poor security, therefore, an encryption control technology for secure transmission of sensitive data in low-voltage transmission network based on transparent encryption is proposed. The sensing request is sent to the root node with the smallest distance from the base station of the transmission network through homomorphic encryption, and the received sensing command is transmitted to the lower child nodes. Then, the random key is formed by pre-processing the homomorphic encryption key pool, and the homomorphic ciphertext is generated by using the index value theory to realize the encryption control of sensitive data. Nextly, transparent encryption combined with piecewise logistics chaotic arrangement is introduced to transparently encrypt sensitive data, and an encryption authentication protocol for network secure transmission of sensitive data is constructed to realize data encryption control. Experiment results show that the improved method can ensure low node cracking rate, and the information readability is higher than 99%, which could protect user privacy and data security.
