Abstract

This invention relates to one software protection device data transmission process safety control method, which comprises the following steps: sending the data between computer and software protection device by code form to make the whole process data without clear data in the communication circuit; due to random interference type and coding process of data, it makes each same order sent from protection software into software protection device and the feedback order from software protection device is variable.

Description

technical field [0001] The invention relates to a safe transmission method, in particular to a safe control method for the data transmission process of a software protection device. technical background [0002] With the continuous development of computer technology, software oriented to the needs of various application fields or industries is continuously born. But no matter what kind of excellent software, its internal core technology is often the lifeblood of the software. Once it is stolen or illegally copied by others, the resulting economic losses are immeasurable. [0003] As an information security device, software copyright protection products play an important role in the field of software copyright protection. It protects the interests of software developers, increases revenue, protects the interests of legitimate users, and can also control software distribution. Prevent the piracy that will be faced after the sale, and cannot regularly collect software usage fe...
