摘要 |
An apparatus for providing smart card security may include a processor. The processor may be configured to determine, for a mobile terminal locked to a smart card, whether a temporary subscriber identifier is being read from the smart card or whether the mobile terminal is receiving a new temporary subscriber identifier from a network in communication with the mobile terminal, compare a network identifier associated with the temporary subscriber identifier to a network identifier included in a permanent subscriber identifier associated with the smart card in response to a determination that the temporary subscriber identifier is being read from the smart card, compare a network identifier associated with the new temporary subscriber identifier to a network identifier associated with a previous temporary subscriber identifier in response to a determination that the new temporary subscriber identifier is received from the network, and determine whether to invalidate the temporary subscriber identifier or the new temporary subscriber identifier based on a result of a respective one of the comparing operations. |
