摘　　要：分布式数据库系统是新近发展起来的一种技术,虽然其有效的维护和管理庞大的数据库,提高了数据库的可用性和可靠性,但由于分布式数据库大多存放海量的重要数据,因此其安全性越来越重要。从分布式数据库的特点入手,分析了分布式数据库加密的层次和流程,并对分布式数据库的关键影响因素进行了详细分析。最后指出了分布式数据库安全现存的问题和将来研究的方向。Distributed Database System is one of technologies developed recently, Although its effective maintenance and management numerous databases have advanced the usability and security of the distributed database, its security is more import because of it storaging a great deal of momentous datas. From the distributed database＇s trait, its encrypting levels and flow are analysed, and labored its import influencing factors. At last the existing problems of distributed database security are proposed and the future research directions are also indicated,
