Method for directly and arbitrary separating code to encryption lock from software to implement protection of software protection

Abstract

The invention provides a method for separating code to an encryption lock from an executable file directly comprising separating code to an encryption lock from an executable file directly, setting a clock timer and a random number generator in the intelligent card encryption lock, filling an interactive code for communication with the encryption lock in the vacancy of the executable file after the code is separated, the encryption lock dynamically decomposing, encrypting and protecting the code that is separated into the lock and needed to be executed continuously by using a specific protocol and algorithm, wherein a plurality of blocks are generated and the release of the block is determined by the normal executed time of the previous block, if the request for demanding the next block sent from the interactive code arrives in the encryption lock in the normal time period, an effective information will be released from the encryption lock, if not, an ineffective information is released. Moreover, a layer of encryption lock filter drive program is added to the encryption lock and the interactive code. Thereby, the illegal monitor and interception of the communication data in the communication link and system are prevented.

Description

technical field [0001] The invention belongs to the field of computer security, in particular to an encryption lock for copyright protection of computer software. Background technique [0002] In today's information age, information processing technology with computers as the core is in an absolute leadership position, which has a huge impact on the development of human society, the improvement of the national economy and the changes in people's lives. The computer software is the soul of the computer system, controlling and directing various operations of the machine. [0003] Since the birth of software, software piracy has accompanied it, seriously damaging the legitimate interests of workers and disrupting the social and economic order. At the same time, software copyright protection products to fight against software piracy have also emerged, mainly the initial pure software encryption and the later encryption lock. With the continuous progress and development of tech...

Problems solved by technology

But most of the software rarely has codes of pure operation, even if there are codes, they can be used by decryptors to prevent real or simulate;

[0007] 2. Software authors need to spend a lot of time to learn and master the use of encryption locks and software encryption technology

[0008] 3. The development environment interface provided by the encryption lock using this technology does not fully support various program development environments on the market today.
