Authentication method based on wireless signal intensity

Abstract

The invention discloses an authentication method based on wireless signal intensity. The wireless signal intensity of wireless network equipment is read, whether the wireless signal intensity reaches a set threshold value or not is judged, the equipment is authenticated when the wireless signal intensity reaches the threshold value, and the wireless signal intensity continues being read and judged if the wireless signal intensity does not reach the threshold value; in addition, the threshold value can be corrected according to the network equipment of different kinds, and the method is more flexible and more convenient to implement. By the adoption of the technical scheme, the method can be combined with a secret-key-free open network mechanism, cooperation of the secret-key-free open network mechanism and a mobile communication equipment short message authentication mechanism, a WEP encryption authentication mechanism, a WPA encryption authentication mechanism, a WPA2 encryption authentication mechanism and a WPS encryption authentication mechanism, and is an effective measure for further enhancing safety.

Description

technical field [0001] The invention relates to an authentication method based on wireless signal strength. Background technique [0002] The general standard for wireless networks in the world today is the IEEE 802.11 wireless network communication standard defined by the Institute of Electrical and Electronics Engineers (IEEE) in 1997 and related supplementary standards released thereafter. The IEEE 802.11 standard provided a keyless open network mechanism and an authentication mechanism for Wired Equivalent Privacy (WEP) in the early days. However, due to serious security problems in wired equivalent encryption, the IEEE 802.11 standard added encryption authentication mechanisms called "WPA" and "WPA2" by the market in the IEEE 802.11i standard supplemented in 2004. Although the Institute of Electrical and Electronics Engineers developed the IEEE 802.11 standard, it is a commercial alliance called the Wi-Fi Alliance that is driving this standard to the market.

AI Technical Summary

Problems solved by technology

Wired Equivalent Privacy (WEP) was found to have serious security problems in 2001: when there is a user connection, the encryption key can be obtained within an acceptable time

[0008] WPA and WPA2 encryption authentication mechanism solves the security problem of wired equivalent encryption, but its encryption operation is cumbersome and the convenience is relatively poor

[0009] Wi-Fi Protected Setup (WPS) is a wireless security standard proposed by the Wi-Fi Alliance to improve the convenience of WPA and WPA2, but this standard was found to have serious security problems in 2011: in the wireless signal Under acceptable circumstances, it only takes one day to get the encrypted key

[0010] Keyless open network mechanism, keyless open network mechanism with mobile communication device short message authentication mechanism, Wired Equivalent Privacy (WEP) encryption authentication mechanism, WPA encryption authentication mechanism, WPA2 encryption authentication mechanism and Wi-Fi protection settings (WPS) encryption authentication mechanism has the problem of poor convenience or poor security
