Abstract: This article aims to systematically explore the verification algorithms applied in smart meters and conduct in-depth analysis of them. The paper analyzed the demand for smart meter data verification, clarified the importance of data accuracy, and highlighted the challenges faced by verification algorithms. Subsequently, the paper classified and discussed various verification algorithms, including those based on error detection and error correction, and provided a detailed analysis of their working principles, advantages, and disadvantages. In terms of design and implementation, the paper proposes the design principles of verification algorithms and explores their specific implementation methods in smart meters, solving the technical difficulties encountered during the implementation process. In addition, through case analysis, the paper evaluated the actual effectiveness of different algorithms and proposed improvement suggestions.
