Embodiment Construction

[0018] The embodiment of the software distribution and encryption method that the present invention proposes is described as follows in conjunction with accompanying drawing:

[0019] The mobile storage of the present embodiment adopts the large-capacity mobile storage of the universal serial bus interface in the applicant's utility model patent 01200990.3, realizes the storage and encryption method of issuing software with it, as figure 1 As shown, wherein, the mobile memory is connected to the computer through an external bus interface such as USB, 1394 or Bluetooth interface. The said mobile memory is mainly composed of a single-chip microcomputer and a chip-based storage medium, and the single-chip microcomputer runs corresponding software to realize the communication with the computer. Communication, read and write memory, and implement data decryption and decryption algorithms. On the computer side, the user's application program can communicate with the mobile storage t...

Abstract

The invention related to computer technique area. It uses removable storage based on computer external bus interface as storage media for distributing software. The data with different security requirements are stored in three areas, that are common area, read only area and system area. The common area can be read out and written in. Using communication protocol of standard removable storage, can be accessed the common area and read only area. But the system area can be accessed only by special communication protocol defined between encipher and decipher modules on computer end and encipher and decipher modules on the end of removable storage. The removable storage itself possesses enciphering capability by hardware. The invention provides merits of high security, easy operation and lower cost.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a software distribution and encryption design method based on mobile memory. Background technique [0002] At present, software distribution generally adopts floppy disks or CD-ROM media for distribution, and at the same time cooperates with the use of dongles to encrypt and prevent piracy. This traditional approach to software distribution has significant limitations. First of all, the floppy disk has poor reliability, small capacity, only 1.44MB, and slow transmission speed; although the CD-ROM has a large capacity, it is a read-only medium, so software and data must be installed on the hard disk to run, which brings great hidden dangers to data security. ;Secondly, the storage of floppy disks and CDs does not have security, and its encryption must be carried out by an independent dongle, which is complicated to operate and very expensive.
