Study And Implementation Of Secure Electronic Ticket System

Since there is inadequacy in the scenic spots and secure problems of the electronic ticket system, the thesis tries to make a tentative study about the relevant technology of data encryption and the identification of secure electronic ticket system.The thesis adopts the system with three-leveled database construction model enciphering the outer space of DBMS and using database secure identification & the daemon threads between client and service in the project of secure electronic system design, which realize the secure identity identification and data transfer between client and service.After analyzing the current encryption technology, the thesis makes a contrastive analysis about the usual encryption methods. And then, the thesis enciphers data from systemic database using AES, on the basis of the requirement of database system. That is, the use of "Cipher Message Movement" has solved the problem of data length variation of AES encryption algorithm after being enciphered. Therefore, the weak point of the security of AES algorithm has been broken through by using "Secret Key Expansion" .Identity identification and the daemon threads are the key technology of the system. The thesis provides a detail introduction about the working principle and the identification process of identity identification based on secure remote password protocols, which make up dictionary attack and replay attack in the data, strengthen the safety quality of the system, integrate SRP protocol with safe electronic ticket system, and transfer the data encryption between client and service using database service daemon threads.The thesis discusses the method of Two-Phase Secret Key Management Scheme and Secret Key Resultant of the system, which is an important...
