METHODS, APPARATUSES, AND COMPUTER PROGRAM PRODUCTS FOR LOCKING A REMOVEABLE DEVICE TO A SPECIFIC HOST DEVICE

摘要

A method, apparatus, and computer program product are provided, which may lock a removable device to a specific host device. An apparatus may include a processor configured to establish a plurality of challenge-response pairings with a locked subscriber identity device. The processor may also be configured to select an unused challenge-response pairing from the plurality of challenge-response pairings. The processor may further be configured to mark the selected challenge-response pairing as used. The processor may additionally be configured to send the challenge from the selected challenge-response pairing to a connected subscriber identity device and receive a response from the connected subscriber identity device. The processor may also be configured to determine whether the connected subscriber identity device is the locked subscriber identity device based at least in part upon a comparison of the received response to the response in the selected challenge-response pairing. Corresponding methods and computer program products are also provided.
