Method for acquiring WLAN accessing one-time password

Abstract

This invention discloses a method to get one time code OTP of WLAN joining through non-structure compensation operation data USSD, which comprises the following steps: step A, the mobile communication mobile terminal applies to the hitch location register for OTP code through standard USSD orders in the mobile communication net; step B, HLR and attestation server in WLAN interacts through standard USSD orders and send the current contract data to AS; AS generates OTP code according to contract data and then sends it to HLR; step c, HLR sends the OTP code got from step B to the current mobile terminal through standard USSD orders.

Description

technical field [0001] The invention belongs to the technical field of security authentication, and in particular relates to a method for obtaining a one-time password (OTP) for accessing a wireless local area network (WLAN) through an unstructured supplementary service data (USSD) service. Background technique [0002] WLAN is currently one of the most popular technologies in the information field, and it is also a widely used wireless access method at present. For GSM network operators, combining WLAN network services with GSM networks is not only conducive to the promotion of WLAN services, but also solves the problem of WLAN user billing. More importantly, GSM network operators can use this Therefore, it will be very valuable to combine the WLAN network with the GSM network to develop new services without changing the network elements in the existing GSM network. [0003] For WLAN networks, with the construction of large-scale hotspots in the network and the acceleratio...

Problems solved by technology

[0004] 1. The access authentication method with fixed user name and password. This method uses a fixed user name and password to realize the access process. In different access processes, the user name and password used by the user remain unchanged. However, since the user uses a fixed username and password, it is easy to cause losses when the username and password are stolen;

[0005] 2. Extensible Authentication Protocol (EAP)-Subscriber Identity Module (SIM) access authentication method, which uses the SIM card to achieve unified authentication and billing, but it has the disadvantages of inconvenient use and relatively complicated operation;

However, for the above-mentioned situation where the WLAN network is combined with the GSM network, there is no solution for the OTP access authentication method corresponding to this network application environment in the prior art
