Software protection method and device and software protection lock

Abstract

The invention discloses a software protection method and device and a software protection lock. The software protection method is used for protecting software and comprises the steps that when software is started, the software protection lock associated with the software is detected; when the software protection lock is detected, a permission associated with the software is loaded into the software protection lock, so that the permission is verified through the software protection lock; corresponding operation is performed on the software according to the verification result. According to the method, the permission does not need to be placed in the software protection lock, so that the situation that the permission is illegally modified by others obtaining the software protection lock is avoided, and interests of a software manufacturer are guaranteed; a user can use a plurality of pieces of protected software by only using one software protection lock, and the use cost is reduced.

Description

technical field [0001] The invention relates to the field of digital encryption, in particular to a software protection method, device and software protection lock. Background technique [0002] At present, in the field of digital encryption of software, due to security considerations, software licenses are generally stored in software protection locks, and the licenses are generally unreadable and unmodifiable. From the perspective of the characteristics of the license, the license itself only needs to be guaranteed not to be tampered with by a third party or maliciously used to ensure its security. From this point of view, the traditional way of storing licenses with software protection keys has many inconveniences. [0003] 1. The storage space of the software protection lock is limited. Due to technical limitations, the storage space of the software protection lock is extremely small. The storage space basically does not reach the mega-level software protection lock, and...

From the perspective of the characteristics of the license, the license itself only needs to ensure that it is not tampered with by a third party or maliciously used to ensure its security. From this point of view, there are many inconveniences in the traditional software protection lock storage license

[0003] 1. The storage space of the software protection lock is limited. Due to technical limitations, the storage space of the software protection lock is extremely small. The storage space basically does not reach the mega-level software protection lock, and the number of storage licenses is limited. The space can store 6,000 licenses, but if the license has a data area, the storage space of the software protection key will be very crowded so that too many licenses cannot be placed in the storage space

[0004] 2. Users buying too many software protection locks will cause waste. Users sometimes need to purchase software from multiple software developers. Each software needs a software protection lock, and the license configuration in the software protection lock is fixed. It is not necessarily necessary to use all licenses at the same time, that is, for users, purchasing too many software protection locks will cause a waste of resources

[0005] 3. Security. Once the license is placed in the software protection lock, it is difficult for software developers to modify it, and others can set the terms of the software license to use indefinitely through illegal channels, which will affect the software. Developers do a lot of damage
