【摘要】 从数据库加密的几种常见的方法出发,重点介绍数据库外部加密办法以及它的优缺点,然后再介绍非对称加密算法——RSA算法以及它的优缺点,接着说明把RSA和数据库外部加密相结合的新的数据库加密优点,最后介绍将流行的J2EE框架Spring+Hibernate+Struts应用于该模型的实现方法和PostgreSQL数据库在Linux的移植.更多还原

【Abstract】 Starting with some methods of encoding database,the paper mainly introduces outward encoding database way,as well as its goods and shortcoming and then the unsymmetrical encoding algorithm and its merit and demerit.Hence,the merit of RSA linking with outward encoding database was recommended.Lastly,the popular J2EE frameset,Spring+Hibernate+Struts,was applied in the modules,as well as postgre SQL database installing in linux OS.更多还原
