Problems solved by technology

[0003] While improving the security of the business system, it will inevitably increase the delay of the business system interaction, and the number of IoT terminals is large, and the access pressure of the secure access device is huge, and a large amount of processing information is likely to cause the device to be paralyzed, which has a negative impact on the business system. affect the overall operation
At present, in view of the bottleneck problem of the number of terminal access, the industry mostly adopts the cluster deployment mode of security access devices. By increasing the number of security access devices to meet the access requirements for the number of terminals, this increases the cost and brings Here Comes the Difficulty of Management

Abstract

The invention discloses a real-time high-concurrency safety access device and an access method for a intelligent energy service system. The method comprises the steps: selecting a specific gateway module according to the CPU utilization rate of the gateway module after an agent module is connected with a terminal, and transmitting a session application message to the selected gateway module; establishing data communication connection between the selected gateway module and the terminal; after the gateway module establishes a communication connection with the terminal and before data interaction, adopting a preset encryption algorithm to carry out bidirectional identity authentication and key negotiation; and decrypting the ciphertext data based on a preset value, checking the decrypted filling message, and establishing data communication connection with a master station system after the checking is passed. The gateway modules are selected through the agent module according to the CPU utilization rate of the gateway modules, the access requirements of a large number of terminals are met, the processing efficiency is improved, and the communication delay is reduced.

Description

technical field [0001] The invention relates to a real-time high concurrent security access device and an access method for a smart energy service system, specifically belonging to the technical field of network security access. Background technique [0002] With the rapid development of the Internet of Things, there are many types of Internet of Things terminals, such as electric meters, charging piles, and inspection robots in the energy field. At the same time, a large number of IoT terminals are connected to the main station system and interact with it. Due to the wide distribution and large number of IoT terminals, with the future business development, the number of terminals will only increase. Therefore, at a certain time, the system equipment will face a large number of terminal access requests and the communication pressure of uplink and downlink data information. It is necessary to ensure the timeliness of data transmission and reduce communication delays. In add...
