基本解釋

Second, studying into the theories aroundingdatabase-encryption system , explaining the cryptograph index, key management and some other key technologies in detail;
接著深入研究了數(shù)據(jù)庫加密系統(tǒng)的相關(guān)理論，對(duì)密文索引、密鑰管理等數(shù)據(jù)加密系統(tǒng)中的關(guān)鍵技術(shù)給出了詳細(xì)的闡述；
Although achievements have been made, there still are problems of long responding, expensive cost and low security of cryptograph index after encrypted that are not solved yet.
針對(duì)數(shù)據(jù)庫中數(shù)據(jù)的保密性問題，分析了目前已有的一些加密機(jī)制，提出了一種基于密文索引的新的查詢方法。
