Electronic Business Financial Data Encryption Method Based on AES Algorithm

当前电商财务数据加密测算多为单元独立加密的形式计算，目标加密效率较低，导致最终加密速率降低，为此提出对基于AES算法的电商财务数据加密方法的设计与分析。结合当前的测定需求，先进行财务数据加密密钥扩展，展开轮密钥加密处理，结合AES算法，提升目标加密的实际效率，构建AES测算电商财务数据多轮加密模型，采用输出密文及动态解密的方式完成数据加密处理。测试结果表明：对比于传统新型真随机数财务数据加密方法、传统加权傅里叶变换数学模型财务数据加密方法，此次所设计的AES测算电商财务数据加密方法最终得出的加密速率相对较高，这说明通过AES算法的辅助与支持，设计的加密方式更为具体、加密覆盖范围扩展，加密速度与效率大幅度提升。
At present, the calculation of e-commerce financial data encryption is mostly calculated in the form of unit independent encryption, and the target encryption efficiency is low, resulting in the reduction of the final encryption rate. 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.
