Abstract
The invention discloses a user authentication method and a user authentication device, which are applied to a network environment comprising a home location register / authentication center, a mobile switching center / visited location register, and user equipment taken as a calling user. The method comprises that: an update period of the shared confidential data of the calling user is preset; after returning the position information about a called user to the calling user by the home location register / authentication center, and if the last update time of the shared confidential data of the calling user exceeds the update period and the calling user is preset to cancel the share of the shared confidential data after the last update time exceeds the update period, the home location register / authentication center receives an authentication request transmitted by the calling user via the mobile switching center / visited location register, and authenticates the calling user; and if the callinguser does not pass the authentication and does not access a network for the first time, the calling user is determined to be illegally cloned. The user authentication method and the user authentication device prevent the user from being illegally embezzled for a long time.
Description
technical field [0001] The present invention relates to the communication field, in particular to a user authentication method and device. Background technique [0002] In a Code Division Multiple Access (CDMA for short) network, the Home Location Register (Home Location Register, HLR for short) / Authentication Center (AUC for short) and the terminal device record the / AUC The shared secret data (Shared SecretData, referred to as SSD) of the mobile user who places the number, the SSD is used for the calculation of the authentication result (AUTHR) by the network and the terminal device in the authentication process (AUTHREQ), and for the terminal device Carry out legality checks and reject illegal users from accessing the network. [0003] For the SSD, when the terminal device accesses the network for the first time and the authentication fails, it can be selectively updated, or the network side can actively trigger the SSD update. In the case of successful authentication, ...
