Abstract

Disclosed are a method for authenticating a universal subscriber identity module (USIM) and a system thereof. The method for authenticating a universal subscriber identity module according to one embodiment of the present invention comprises: a step of determining whether the memory address for the USIM is stored when a USIM authentication-related message is received through a switch; a step of updating the memory address to a first memory address in which the memory address is increased by a predetermined value, if it is determined that the memory address is stored; a step of generating an authentication vector including the first memory address; and a step of transmitting the authentication vector to the USIM via the switch such that the USIM performs an authentication using the authentication vector.

Description

technical field [0001] The present invention generally relates to a method and system for authentication of a Universal Subscriber Identity Module (USIM), and more particularly to a system and method for authenticating a USIM, which can prevent authentication failure and impossibility of call service, authentication failure and call service impossibility may occur due to partial corruption of the memory provided in the USIM during the Authentication Algorithm (Authentication and Key Agreement: AKA) for the Universal Mobile Telecommunications System (UMTS), and it may also reduce the possibility Costs incurred by replacing USIM. Background technique [0002] In International Mobile Telecommunications 2000 (IMT-2000) which is a third-generation mobile communication scheme (for example, Wideband Code Division Multiple Access (WCDMA)), and in which is a second-generation mobile communication scheme and has compatibility with IMT-2000 Authentication has been standardized in the ...
