| 摘 要： | 数据库加密中,主要采取敏感字段的加密设计机制,敏感字段同密钥一一对应,但如果所有的密钥全部预设势必产生新的安全问题.因此,数据库加密密钥如何产生及保管便成为重中之重.为此,可以采取一种密钥派生机制,实行二级密钥管理,包括管理密钥与加密密钥.加密密钥用于加密敏感字段,它是通过DES加密算法,对管理密钥进行的16轮加密迭代...

| Abstract: | One encryption design mechanism based on sensitive fields is mainly adopted in database encryption,which sensitive fields is correspondence to keys one by one.But if all the keys are fixed in advance,new security problem will emerge.So how to generate and save the encryption keys is of grent importance.One derivative echanism of two-stage encryption key is adopted,including management keys and encryption keys.encryption keys which come from the transformed results in sixty round of DES encryption algorithm ... |
