摘要
为了使敏感数据在存储期间的机密性得到有效保障,在分析数据库加密粒度的基础上,提出一种基于AES的加密算法对敏感字段进行加密存储,并针对密钥的隐蔽性提出建议,从系统存储层上保证数据的安全性。
To ensure the confidentiality of sensitive field in the storage period, based on the analysis on the granularity of database encryption, a based AES encryption algorithm is proposed to encrypt stored sensitive field. Recommendation is made for hidden keys. Thus the security of data from the storage layer of system is assured.
