Research on the Security Verification and Evaluation System of Distribution Network Dispatching Instructions in Telephone Mode

Nowadays, the issue of command security in the distribution network dispatching telephone command mode is becoming increasingly prominent, and relevant personnel are paying more and more attention to the information security and accuracy when transmitting dispatching instructions to the distribution network, to prevent risks such as tampering, forgery, and theft of dispatching instruction information. The article first briefly analyzes the problems that exist in the telephone command mode during scheduling; Secondly, in response to the data security issues related to the issuance of instructions in the distribution network, based on cloud storage technology, the S-box is improved in the group encryption algorithm AES, and a chaotic system is introduced for data sequence encryption. The improved AES algorithm is combined with the chaotic system to achieve confidentiality of both parties' codes and information transmission; Simultaneously introducing upper entropy, using entropy to randomly verify the completeness and accuracy of numbers or information; Finally, the effectiveness of this method was theoretically proven, achieving efficient communication of scheduling information and ensuring the confidentiality and accuracy of received scheduling instructions.
