SECURE ESTABLISHMENT METHOD, SYSTEM AND DEVICE OF WIRELESS LOCAL AREA NETWORK

摘要

The embodiments of the present invention provide a secure establishment method, system and device of a wireless local area network. The method includes: acquiring, by a UE, a first key; the first key is a shared key of the UE and a network element equipment in a mobile communication network to which the UE is accessed when implementing air interface security, or is derived according to the shared key; deriving, by the UE, according to the first key and a derivation parameter to acquire a derivation key; establishing, by the UE, according to the derivation key, secure connection with a WLAN node acquiring a derivation key, wherein the derivation key acquired by the WLAN node is the same as the derivation key acquired by the UE.

1. A method of establishing a secure connection in a wireless local area network, comprising:
acquiring, by a user equipment, a first key, wherein the first key is a shared key of the user equipment and a network element equipment in a mobile communication network which the user equipment accesses when implementing air interface security, or wherein the first key is derived according to the shared key of the user equipment and the network element equipment in the accessed mobile communication network when implementing the air interface security; deriving, by the user equipment, according to the first key and a derivation parameter a first derivation key, wherein the derivation parameter is determined by consultation between the user equipment and the network element equipment; and establishing, by the user equipment, according to the first derivation key, a secure connection with a wireless local area network node acquiring a second derivation key, wherein the second derivation key acquired by the wireless local area network node is the same as the first derivation key acquired by the user equipment.
