Softdog device and secondary authorization management method based on softdog

Abstract

The invention relates to the field of information technology security, and in particular relates to a softdog device and a secondary authorization management method based on a softdog. A hardware and software combined softdog having a secondary authorization function comprises a USB interface, a USB-serial interface converter, a single-chip microcomputer and a power supply; and furthermore, the softdog has the secondary authorization management permission. The method comprises the following steps of awarding a mother softdog having the secondary authorization permission to an industry algorithm library; completing compiling and encapsulation of the industry algorithm library by using the mother softdog; activating the secondary authorization function by using the mother softdog, and authorizing a child softdog; copying the industry algorithm library into a child softdog workstation; and calling and using the copied industry algorithm library by using the child softdog. By means of the softdog device and the secondary authorization management method based on the softdog disclosed by the invention, the risk that the industry algorithm library having the proprietary intellectual property is leaked can be put an end; and information security is also ensured while the programming workload is greatly reduced.

Description

technical field [0001] The invention relates to the field of information technology security, in particular to a dongle device and a secondary authorization management method based on the dongle device. Background technique [0002] With the rapid development of science and technology, the degree of automation of the production system is getting higher and higher. The smarter the system, the higher the efficiency and the lower the labor cost. The intelligence of the system depends not only on the hardware of the production system, but also on the brain of the intelligent system—the software program. The biggest feature of the software is its portability, which brings convenience to developers and prevents software copyright from being obtained. At the same time, it also brings security risks to the data information of the industry algorithm library with independent intellectual property rights. [0003] Software dongle is an intelligent tool with software protection functio...

Problems solved by technology

At the same time, the dongle is used along with the software platform, which means that as many operating stations run the software platform, as many dongle devices are needed. The trouble caused by this model is the management of the dongle, and there is also a cost. High and poor flexibility
