Embodiment Construction

[0032] In conjunction with above-mentioned accompanying drawing, the present invention is described in further detail:

[0033]Step 1. When the terminal STA initially accesses the WLAN network, assuming that the STA is associated with the access point AP1, the STA and the authentication server AS pre-negotiate the handover key HK and the handover key ID HKID during the initial access authentication phase. Methods include IEEE 802.1X and improved WAPI.

[0034] Step 2. When the STA decides to associate with the access point AP2, the STA uses the handover key HK to calculate the handover subkey HK-L1 corresponding to AP2, and uses HK-L1 to calculate the handover message authentication key HMAK.

[0035] The manner in which the STA uses the handover key HK to calculate the handover subkey HK-L1 corresponding to AP2 is as follows, but not limited to the following:

[0036] HK-L1=KD-HMAC-SHA256(HK, "Handover key level 1"|ADD AP2 |ADD STA );

[0037] Among them, KD-HMAC-SHA256 i...

Abstract

The invention provides a method for enhancing the fast handover authentication security of a wireless local land area, which mainly aims to solve the problem that the requirement of military application on high security cannot be met with a conventional standard. The method is implemented by the following steps that: a terminal negotiates a handover key with an authentication server in an initialaccess authentication stage; the authentication server calculates a corresponding handover sub-key when receiving a handover sub-key request transmitted by an access point, and transmits the handoversub-key to the access point; and in a handover process, the terminal and the access point utilize the handover sub-key to perform fast authentication and adopt elliptical-curve-based Diffie-Hellmn handover to generate a session key. The method provided by the invention has the advantages of forward confidentiality, capacity of resisting a part of denial of service attack, key management simplification and key exposure risk reduction, and can be used for the internal internet of emergency communication and a command station, an urban operation network and quick network deployment under a fieldoperation environment.

Description

technical field [0001] The invention belongs to the technical field of network security and relates to a security enhancement method of a wireless local area network, which can be used for emergency communication, internal Internet of a command post, urban combat network and rapid network deployment in a field environment. Background technique [0002] WLAN (Wireless Local Area Network) transmits information through radio waves as a medium, and is the product of the combination of computer network and wireless communication technology. In recent years, with its high-speed transmission capability and flexibility, WLAN has been widely used in civilian fields. At present, it has been used in companies, government departments, schools, hospitals and residential quarters. Wireless local area network not only faces the challenge of traditional wired network attack methods, but also faces the challenge brought by the particularity of wireless network. The broadcast feature of the...
