Embodiment approach

[0056] According to an embodiment, the MEC side gateway performs a second confirmation of whether the device is an abnormal device according to a predetermined condition; if the confirmation result is no abnormality, the device is allowed to access the network. In one example, if a device continuously sends out N abnormal device physical fingerprints within a predetermined time period, the device is confirmed as abnormal device; if more than N abnormal device physical fingerprints do not appear in the predetermined time period If the device is not abnormal, it is determined that the device is not an abnormal device.

[0057] In a specific example, the abnormal information transmitted by the WiFi local gateway can also be stored and comprehensively determined. If a device has more than N abnormal fingerprint samples continuously within a given period of time, the device is considered abnormal. The device then sends the stored abnormal fingerprint samples and their MAC addresses...

Abstract

The embodiment of the present invention provides a wireless device authentication method and its system, the method is based on the core network side gateway, the MEC side gateway and the WiFi local gateway, the method includes: extracting the device fingerprint from the radio frequency signal of the wireless device; extracting the device MAC from the signal data address; according to the MAC address of the device, obtain the pre-stored fingerprint of the device locally; according to whether the device fingerprint matches the pre-stored fingerprint, confirm whether the device is abnormal; if abnormal, send the device fingerprint and MAC address to the MEC side gateway; if the MEC side gateway confirms the If the device is an abnormal device, the fingerprint and MAC address of the device will be sent to the core network side gateway; if the core network side gateway confirms that the device is an abnormal device according to the overall network situation, it will send a blocking command to the MEC side gateway; if it is an access device, send a command to change the fingerprint; the MEC side gateway sends the command to the local gateway to block the access of the device. The invention can effectively identify illegal access equipment, and improves the security of equipment access.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a wireless device authentication method and system based on a distributed security gateway. Background technique [0002] Compared with traditional wired communication systems, wireless communication systems are more vulnerable to malicious attacks due to their openness. In view of the potential security risks in the wireless communication environment, the classic method to solve the problem of air eavesdropping is to encrypt the air data; and the effective method to solve the illegal device access is to authenticate the access device. The traditional encryption and authentication methods to protect the security of wireless communication systems are based on the OSI (Open System Interconnection Reference Model, Open System Interconnection) seven-layer model above the physical layer. Confidentiality protection and authentication of the identity of the ...
