摘要
对数据库中的关键数据加密是保护数据库中数据安全的有效措施。在经过深入研究的基础上提出了一个行之有效的数据库加密服务器的实现方案,在给出的实现方案中,被加密的数据库可以是符合SQL标准的多种常见的关系数据库,加密粒度是表字段,而且密钥管理具有高度的灵活性。为了验证提出方案的正确性和可行性,实现了一个模拟的数据库加密系统。测试模拟系统所得的数据表明本数据库加密系统设计方案切实可行。
It is an effective security measure to encrypt the key data in the database. An effective realization program is put forward on the basis of in-dept research. In this program, the encrypted database can be a variety of common database compliant with SQL standard and the encryption size is a table field, moreover, the key management has a high degree of flexibility. In or- der to verify the correctness and feasibility of this program, a simulation systemi of database encryption system is realized. The data from the testing simulation system reveals that the database encryption system design program is feasible.
