外包密文数据库内容验证及查询机制研究

Research on Content Verification and Query Mechanism for Encrypted Outsourced Database

外包数据库是近年来出现的数据服务新模型,鉴于其特殊的服务模式,其数据安全问题一直备受关注.该文对外包数据库的服务模式及其数据安全保护机制进行了研究和探讨,设计了一种适用于外包数据库的密文数据查询和验证机制,并基于MYSQL实现了一个原型系统证明了该方法的可行性.

Outsourced database is a newly developed data service model.Due to its special service mode,its data security has always been a major concern.The service model and the requirements of data security in outsourced database are discussed in this paper.A content verification and query mechanism for encrypted outsourced database is then proposed and aprototype system is developed using MYSQL which validates the feasibility of the proposed scheme.
