Embodiment Construction

[0022] The technical solutions of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] refer to figure 2 , illustrates a schematic diagram of an application scenario of an embodiment of the present invention. A method for improving air interface security of a wireless communication system and a wireless network device according to an embodiment of the present invention send encrypted normal information to be substantially processed by the terminal (such as a mobile phone) on the network side (such as through a base station). Before or / and after the command, randomly insert a number of signaling that the mobile phone will not perform substantial processing to enhance the security of the air interface, such as randomly inserting a number of invalid signaling.

[0024] Such as image 3 As shown, a method for improving the security of a wireless communication system in an embodiment of the present inv...

Abstract

The invention discloses a method for improving the security of a wireless communication system and the wireless network equipment thereof, wherein the method comprises the following steps: a wireless network side acquires invalid signaling which can not be substantially processed by the terminal; before and / or after normal signaling is distributed, the wireless network side distributes at least one piece of invalid signaling. Correspondingly, the invention also discloses wireless network equipment. Through implementing the method and the wireless network equipment of the invention, the guess difficulty for a hacker is increased, the air interface security of the wireless communication system is enhanced, and the privacy of the communication system is guaranteed.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a method for improving the security of a wireless communication system and wireless network equipment. Background technique [0002] With the wide application of the Global System for Mobile communication (GSM), more and more researchers began to pay attention to the encryption algorithm of the GSM air interface. In 1999, Briceno introduced the A51 encryption algorithm through reverse engineering. Since then, many cracking algorithms for A51 have been proposed, and a considerable part of them adopt the mode of known plaintext attack. , and the ciphertext pair composed of the final data is cracked. If the pattern of the downlink protocol messages is relatively fixed, the possibility of successful guessing by the hacker will be high, and the communication key Kc will be cracked with a high probability, thereby seriously affecting the session security. [0003] In the call ...
