The Files Encryption Tool Based on USB-KEY
—— USB -KEY Management System
Abstract
With the rapid development of IT, the security of the files has been increasingly attention. To implement encryption for important personal information, preventing others that steal personal information, improving the security of the document, encryption has been a very important topic.
This design aims to solve the problem that users passwords are remembered difficulty, implement the functions of encryption and decryption for documents by the combination of software and hardware. It has many characteristics, such as simple, stable, good compatibility, speed and so on. The system uses Rockey2 USB Key, developed with Delphi. This system has two parts, one part mark is the document encryption deciphering; another part of the administration implement being to encrypt a lock. The queen part is completed by me.
This paper introduces the brief design, detailed design, the application and coding of USB KEY file encryption tool. It introduces the requirements analysis, the system selection for the design, and Rockey2 encryption in the brief design. And it introduces the main functions of the system analysis, the memory allocation of encryption Rockey2, and the related database design in the detailed design. Besides, in the aspect of application and coding, it main introduces the hardware installation, initialization, writing users’ name, passwords for application and coding, and design of management interface, operation of the database. Finally, it introduces the shortcomings of the system and how to improve it.
