Therefore, this paper proposes the design and analysis of e-commerce financial data encryption method based on AES algorithm. Combined with the current measurement requirements, the financial data encryption key expansion is carried out first, the round key processing is carried out, and the actual efficiency of target encryption is improved by combining the AES algorithm, and the AES multi-round encryption model is constructed to measure the financial data of e-commerce, and the data encryption is completed by the output ciphertext and dynamic decryption. The test results show that: Compared with the traditional new true random number financial data encryption method and the traditional weighted Fourier transform mathematical model financial data encryption method, the designed AES calculation of e-commerce financial data encryption method finally obtained a relatively high encryption rate, which indicates that with the assistance and support of AES algorithm, the designed encryption method is more specific and the encryption coverage is expanded. The encryption speed and efficiency have been greatly improved.展开更多
