METHOD FOR DETECTING ILLEGAL ACCESS POINT

摘要

A method for detecting an illegal access point is provided to prevent an access attempt of the illegal AP by registering the illegal AP(Access Point) in a USIM card. A mobile terminal(200) obtains ID information of an AP(300) to be accessed. The ID information for the AP to be accessed is encrypted by using a USIM(Universal Subscriber Identity Module) card(100), and the encrypted result is transmitted to an authentication server(400). An encrypted verification result for the AP to be accessed is received from an authentication server and the verification result is decrypted by the USIM card. The access attempt to the AP is blocked or permitted according to the decrypted verification result.
