Problems solved by technology

[0005] Specifically, the 0th, 1st, and 2nd-level keys are derived during the initial authentication, and then the 1st-level and 2nd-level keys are re-derived when a network switch occurs. Since there may be multiple access devices in the network, each time Switching requires re-exporting the first and second level keys, which complicates the network switching process and reduces the efficiency of wireless network switching

Embodiment Construction

[0038]In the wireless communication network, taking the wireless local area network WLAN as an example, the access device is the wireless access point AP, which converts the wired electrical signal into a radio signal and sends it out to form the coverage of the wireless network. The bridge connects the wireless network to a wired network such as Ethernet, and the requesting device STA in the coverage area of ​​the wireless network can connect to the network through the AP.

[0039] In order to expand the coverage area, APs can often be interconnected. As users move, STAs often need to switch between APs and maintain network connections. As the requirements for STA handover delay between APs become more and more stringent, a fast handover mechanism based on hierarchical keys is proposed in the IEE802.11 series of specifications. Then the AAA Server sends the master key to the AP, and then conducts hierarchical export. During each switching process, the first and second level ...

Abstract

The invention discloses a wireless network switching method, and the method comprises the steps: enabling a request device and a target access device to directly generate a message integrity verification key through a domain key, carrying out the verification of an integrity verification code based on the message integrity verification key, thereby achieving the identity authentication of two parties; when the identity authentication of the two parties is passed, generating the session key by combining the domain key with the random numbers of the two parties, so the switching process is simplified, and safe and efficient network switching is realized. The invention also discloses corresponding request equipment and access equipment.

Description

technical field [0001] The present application relates to the communication field, and in particular to a wireless network switching method, a requesting device, and an accessing device. Background technique [0002] With the development of portable mobile terminal equipment such as mobile phones and tablet computers, wireless communication technology has gradually become one of the mainstream communication technologies. In a wireless communication network, the coverage of a wireless access device is limited. Therefore, switching of the wireless access device often occurs during the moving process, and the time delay generated during the switching process directly affects the communication experience. [0003] When a mobile terminal device accesses a wireless communication network for the first time, it needs to perform a complete initial identification process with a wireless access device, and this process may be called initial mobility domain association. The wireless ac...
