Abstract

The invention discloses equipment for traffic guidance information security management. The equipment is characterized by comprising encryption authentication equipment ICM-A and decryption transmission equipment ICM-B; and the design for adopting modular development and universal cryptographic service API (Application Program Interface) is realized. The equipment for traffic guidance information security management, disclosed by the invention, has the advantages that 1) valid authentication is carried out on guidance information received by traffic information nodes; 2) data displayed by the information nodes is protected; and 3) an industrial personal computer is protected. At present, the information security management equipment is directly applied in a display management system of traffic management guidance information of the intelligent traffic field. The equipment solves the contradiction between the actual condition that the information is accessed into a traffic display screen by an open network and the public information opinion security requirement.

Description

technical field

[0001] The invention relates to the field of information security equipment development, in particular to equipment for traffic guidance information security management. Background technique

[0002] In the existing traffic guidance information system in our country, the guidance information is generated by the information center of the traffic management bureau and then transmitted to each traffic information display node in plain text through an open network (wireless and wired). Each node is equipped with an industrial computer and a traffic information screen. The industrial computer is responsible for receiving the data from the information center, analyzing commands from it to manage and configure the traffic information screen, and recording the more sensitive data and returning it as a log record. Information center for backup, for future inquiries. Due to deployment and cost considerations, an open network is usually used between the information cen...
