Control system and method with authentication function

Abstract

A control system with authentication function for protecting program inventor developed and device. The system comprises a first device including a executive program for controlling the first device and a first key which has information enciphering function and deciphering function; a second device including a control program and a second key which has information enciphering and deciphering function, connecting with the first device through a communication interface; in addition, enciphered information of the first key must be deciphered by using the second key, and enciphered information of the second key must be deciphered by using the first key, the first key and second key needs to cooperate for authentication and the first device and second device will execute function.

Description

Control system and method with authentication function technical field The present invention relates to an authentication device and its related method, in particular to an authentication device and method capable of protecting the program and equipment developed by the inventor, and in particular to a control system with an authentication function. systems and methods. Background technique At present, the common remote-controllable instruments, the control commands are all open on the standard communication interface, and those who are interested can use the ready-made software as long as they design the same command format, resulting in the loss of the development software instrument manufacturer; some instruments Manufacturers will use special communication interfaces to avoid plagiarism, but the development of new communication interfaces will also increase the cost of development and the difficulty of maintenance. As for the software part, common protection methods s...

Problems solved by technology

Although the above-mentioned existing technology can achieve the function of encryption and decryption, because its encryption and decryption procedures are fixed patterns and cannot be changed randomly, and in this system, identification data must first be used to identify the device to which it belongs. The device uses the backup password to confirm the action. It only has a one-way protection mechanism during encryption and decryption, and the set password cannot be dynamically changed; therefore, the general existing technology cannot meet the needs of users.
