  • Method for authenticating a universal subscriber identity module and system thereof
    Patent number: 8611857
    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.

  • METHOD FOR AUTHENTICATING A UNIVERSAL SUBSCRIBER IDENTITY MODULE AND SYSTEM THEREOF
    Publication number: 20120282898
    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 date mining 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.
