中文摘要:针对预制舱变电站物联网建设中存在的信息泄露和隐私保护问题,提出了一种基于超混沌数据的加密算法。即首先利用混沌发生器生成随机序列,其次对序列进行归一化处理,接着利用序列对明文进行掩膜置换等加密操作,最后将密文发送至预制舱变电站服务器,实现数据的加密通信。实验结果和分析表明,该加密算法具有密钥空间大、密钥敏感性强的特点。

Research on Data Encryption Method of Internet of Things Based on Prefabricated Cabin Substation
Abstract:Aiming at information leakage and privacy protection issues in the internet of things communication for prefabricated cabin substations, a hyperchaotic data encryption algorithm based on power Internet of things communication is proposed. Firstly, the random sequence is generated by the chaotic generator, and the sequence is normalized, then the plaintext is encrypted by the sequence, such as mask replacement, finally the ciphertext is sent to the power grid server to complete the communication of the power grid based data encryption system. Experimental results and analysis show that the encryption algorithm has the characteristics of large key space and strong key sensitivity.
