Abstract


safety' dissertation">Information safety has been among one significant real one problem , information safety field being related to a lot of aspect such as country safety and danger , national economy , the people life , public stability , the data base protection has been especially important , information warfare has made a good start of in a single day , success or failure has decided both sides fighting with in fields such as military affairs , politics , diplomacy , economy final. Safe core of information is the data base safety, with computer art develop at full speed, the data base application has arrived at each fields very broad, thorough, has produced but safe data problem in the train of it. In a representative heavy section data base, be sometimes storing large amount of important private data. To mostly legal consumer, this core data base is to store one kind of way very convenient and rapid of key information , benefit brought about by this database should be much bigger but from , breaking directly a solution to come to look at attacker’s angle fishing for the benefit that the data brings about than smelting in the network. On the other hand, pass the broken solution the database, can have burned a visit in one right away to accurate data information. The attacker can feel the interest information simplify by the fact that the data base inquiry gains the person coming order once stealing right from the visit to the data base. ,Just saying the data base encryption is a safe information core problem. Safe database data problem is regarded highly, data base applied technique’s develop the challenge having brought about maximum for data base safety at full speed, the data base safety technology already becomes e-administration network applications restraint factor and function bottleneck on one hand , the effect that another aspect people is aware of to safe cognition of data base by tradition composes in reply the atmosphere effect being commercialized , existence draws have a serious trial with big one-sidedness and limitation. Face this one reality , respond to new theory , new model , new technique and new technology realization method how, to understand and make use of the data base safety? Do if tradition data base safety theory adapt to lower safe Internet environment need? These problem, method and actual technology needing to use a project realize the verification being in progress to these theories and improve and perfect.Database encryption technology application extremely large the problem having resolved data base middle data safety, but the realization method has respectively put particular emphasis on, data base encryption technology method theory principle and technology have realized the main body of a book mainly right away realizing method basically carrying out investigation and discussion , actual application has proposed that to data base encryption to may give supplies to the example drawing lessons.
