摘    要:针对大规模数值型数据库中敏感数据的加密,传统算法无法解决当前行、列数据间加密密钥的干扰问题,导致安全性能较差,效率降低。为此,提出一种新的大规模数值型数据库中敏感数据加密算法,对大规模数值型数据库中的数据进行聚类处理,以过滤无价值数据,得到对用户有价值的数值型数据,降低计算量。给出大规模数值型数据库中敏感数据加密原理,进行大规模数值型数据库的元素级加密,使所有字段的密钥均不相同。介绍了一种只在加密和解密的过程中产生密钥的密钥生成方式,依据得到的密钥对大规模数值型数据库中敏感数据进行加密和解密处理,从而实现敏感数据的加密。实验结果表明,采用所提算法对敏感数据进行加密,不仅能够保证安全性,而且有很高的效率和存储性能。

关 键 词:大规模  数值型数据库  敏感数据  加密

Abstract:in view of the large-scale numerical encryption of sensitive data in the database, traditional algorithm can not solve the current row and column data encryption keys between interference problems, poor safety performance, lower efficiency.For this, put forward a new large-scale numerical sensitive data in database encryption algorithm, for large-scale clustering of numerical data in the database, and to filter data, no value for the user valuable numeric data, reduce the amount of calculation.Large-scale numerical model sensitive data in database encryption principle, elements to carry out large-scale numerical database encryption, makes all the key fields are not the same.Introduces a kind of only produced in the process of encryption and decryption key way of key generation, according to the key of large-scale numerical sensitive data in database encryption and decryption process, so as to realize the encryption of sensitive data.The experimental results show that the proposed algorithm to sensitive data is encrypted, can not only guarantee the security, and has a high efficiency and storage performance.
Keywords:Mass  Numeric database  Sensitive data  Encryption
