Wireless network access authentication system and method based on radio frequency fingerprint and biological fingerprint

Abstract

The invention discloses a wireless network access authentication system and a wireless network access authentication method based on a radio frequency fingerprint and a biological fingerprint. The system provided by the invention comprises a radio frequency module, a radio frequency fingerprint processing module, a fingerprint information storage module, a user information processing module, a fingerprint information authentication module, a connection authentication request sending module, a connection authentication request processing module and an access service module. According to the method provided by the invention, the radio frequency fingerprint of a wireless terminal used by a user for applying for accessing a wireless network is authenticated, after the radio frequency fingerprint is authentication, the biological fingerprint of the user using the wireless terminal to access the wireless network is authentication, and after the biological fingerprint of the user is authenticated, the user is allowed to use the wireless terminal to access the wireless network. According to the system and the method provided by the invention, the secure access to the wireless network is achieved through authenticating the wireless terminal and the user applying for using the network.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a wireless network access authentication system and method based on radio frequency fingerprints and biometric fingerprints in the technical field of wireless network security. The present invention can provide authentication services based on radio frequency fingerprints for wireless terminals used by users to access wireless networks. After passing the biometric fingerprint authentication, the user is allowed to use the wireless terminal to access the wireless network to realize secure access to the wireless network. Background technique [0002] With the rapid development of network and communication technology, wireless network has provided convenience for all aspects of human society, but its broadcast characteristics make the use of the network face security threats. It is very easy for attackers to obtain information such as user names and passwords of legitim...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: first, because this method directly matches the biometric fingerprint input by the user with the biometric fingerprint of the authorized user when performing biometric fingerprint authentication, the attacker can intercept the biometric fingerprint information of the user for further verification. Replay attacks, which threaten the security of wireless networks

Second, this method does not protect the privacy of the biometric fingerprint information input by the user, which will cause the leakage of the biometric fingerprint information of the user.

The shortcomings of this system are: the system only authenticates the biometric fingerprints of the users who use the network, but does not authenticate the terminal equipment used by the users to access the network, lacks a subsystem for authenticating terminal equipment, and users use illegal When the device accesses the wireless network, unauthorized users, that is, illegal users, can steal network information by monitoring and replacing illegal terminal devices

The disadvantages of this method are: first, because the information to be authenticated in this method includes device identification and hardware fingerprint information, when the authentication server receives the information to be authenticated sent by the device to be authenticated, the attacker can intercept the authentication information and re-enable it. release attack

Second, the MAC address and IMEI address in the information to be authenticated can be modified by the attacker, and the attacker can spoof the MAC address and IMEI address to make the illegal device pass the authentication
