The invention discloses a security apparatus, system and method for the on-line upgrading of an industrial control system, and belongs to the field of information security. The apparatus comprises an interface part, a processor, a memory chip, a display device and a button. The processor is connected with the memory chip; the interface part, the display device and the button are respectively connected with the processor; the memory chip is internally provided with a data storage area for storing upgrading software data and a system storage area for storing system data respectively; the upgrading software data is stored in the data storage area; and a file management system is stored in the system storage area. According to the security apparatus, a security algorithm processor connected with a master processor is arranged in the processor, so that when the master processor runs the file management system to carry out such operation as data transmission, secret communication, command interpretation and file management and the like, valid security verification is carried out, and the security of on-line upgrading of the industrial control system is guaranteed. Besides, the size is small, the portability is high, and the upgrading security is improved under the condition that convenience is not affected.
Description
technical field [0001] The invention relates to the field of information security, in particular to an information security device, system and method applied to an industrial control system. Background technique [0002] With the rapid development of Internet of Things technology and industrial automation technology in recent years, software systems such as computer-based production process control, scheduling automation and industrial CAD are widely used in environmental protection, electric power, petrochemical, metallurgy, industrial manufacturing, buildings, etc. in many fields. From a technical point of view, most of the current industrial control systems adopt some high-tech information technology, which continuously improves the stability, interactivity and friendliness of the system itself at the technical level, thereby improving production efficiency and reducing labor costs. However, for some outdated system equipment, there may be serious security holes in the c...
