Method for performing safety controllable remote upgrade for software protecting device

Abstract

The invention provides a safe and controlled remote update method for a software protection device, the method is as follows: control information of a function module update pack is arranged at the terminal of a server and a new function module is obtained; the new function module is encrypted after the control information and the new function module are calculated to obtain calibration information, or after the new function module is encrypted, the control information and the encrypted new function module are calculated to obtain the calibration information; and then the control information, the encrypted new function module and the calibration information are combined to form the function module update pack which is sent to the software protection device; the software protection device check the control information in the received function module update pack, the new function module is obtained after decrypting, the calibration information in the update pack is validated according to the control information and the new function module, and the own update can be performed through using the new function module if the validation is passed. The function module in the function module update pack of the safe and controlled remote update method for a software protection device is all cryptograph in the transmission process, thus the safe and controlled remote update for the software protection device is effectively realized.

Description

technical field [0001] The invention relates to software protection technology, in particular to a method for safely and controllably remote upgrading codes or data of function modules of software protection equipment. Background technique [0002] First give the following definition: [0003] Functional module: the code or data or the combination of the two extracted from the software product by the software developer, which can be or has been set in the software protection device for external calling. [0004] Function module upgrade package: a data package used to upgrade the function modules in the software protection device. [0005] Software protection equipment: the equipment owned by the software developer that is used in conjunction with the software in a certain software product developed by the user. [0006] With the rapid development of economy and technology, software has penetrated into all walks of life as an auxiliary tool. Software products are the cryst...

Problems solved by technology

This seemingly simple process is not easy for software developers. They may need to upgrade the functional modules in the software protection device by door-to-door distribution or recovery of the software protection device, which increases the service cost.

Or the software developer packs the functional modules that need to be upgraded into functional module upgrade packages, and then sends them to the software protection equipment of each user through insecure channels such as telecommunication networks and the Internet, but in this case, the functional module upgrade packages are easy to be eavesdropped and replacement, thus causing great economic losses to software developers
