摘要: 为了防止煤矿瓦斯监控系统中关键数据被篡改，保证数据安全，提出一种在SQL Server 2008数据库中利用对称加密算法对重要字段进行加密，并使用密钥和解密函数还原数据的方法。字段被对称加密后，任何对该字段数据的更改操作都需要得知密钥，并使用解密函数才能实现，从而有效地防止了对关键数据的非法操作，保护了敏感数据。实际应用证实了关键数据加密算法的有效性。

Abstract: In order to prevent critical data of gas monitoring system of coal mine from tampering and ensure data security, the paper proposed a method of using symmetric encryption algorithm to encrypt important field in database of SQL Server 2008 and restore data by key and decryption function. Any changes to the encrypted data cannot be achieved unless knowing the key and using the decryption function, so as to effectively prevent the illegal operation of critical data and protect sensitive data. Practical application confirmed validity of the critical data encryption algorithm.
