| With computer application in social various domains popular, application centering on data base information system has got gradually broad application in business field. At present, since safe data base technology ensures in application system have aroused a lot of inside data leakage phenomenon less than the place. Database is bearing the mission storing and managing the computer system middle data information's, how guarantee and the security reinforcing Database, already have been becoming needing the hot topic of conversation solving at present urgently.On base of encrypt field document in recent years and a telephone billing management system of the development practice, we studied some important technologies of sensitive data encryption in Oracle database, proposing an effective encryption and decryption solution of sensitive information in database, realizing the encryption of sensitive data storage and modification, query, etc. expiring to promote the development of the database encryption technology. The main job includes thesis:First, visiting the customer holds safety. Serve the data base application system under affair implement pattern with the browser being applied or used universally of integration of ASP.NET with ORACLE data base,/the safety resolving customer whole course of visits. And in actual application, hold dynamic usage soft keyboard in the customer, the password carries out an encryption on the consumer, to ensure that the data is transferring security in process.Second, the encryption being that the server holds pair of sensitive data controls. The theorem applying the Chinese surplus theory, probing Chinese surplus adds application in deciphering in the data base especially carries out the security adding deciphering application realizing a server thereby holding sensitive information of data base on sensitive data in data sheet.Third, separation Oracle database server and web server,separation of keys and Oracle database,to ensure that the disclosure of a party in the case of the other party can still be kept confidential. |
