This paper proposes a blockchain-based power communication transmission security risk assessment method,which mainly includes three stages:data collection and pre-processing,risk assessment model construction and evaluation result output and feedback.In the data processing stage,the weight and sliding window algorithm are adopted to ensure the consistency and accuracy of data;in the model building stage,the long-and short-term memory Long Short-Term Memory(LSTM)network is used to process and predict the timing data;in the result verification stage,the Byzantine fault-tolerant Practical Byzantine Fault Tolerance(PBFT)consensus mechanism is adopted to ensure the fairness and consistency of the evaluation results.Simulation experiments verify the effectiveness of this method,and the results show that it can accurately identify the security threats in the power communication transmission system,and significantly improve the overall security level of the system.
