A recently granted patent (Publication Number: US11910198B2) discloses a system and method for securely associating a Subscriber Identity Module (SIM) with a mobile device. The system involves a mobile device with a SIM, a Mobile Network Operator (MNO) computer, and a computer linked to the device owner. Upon the first use of the mobile device, the SIM securely transmits information to the MNO computer, which then records this data with the owner's computer. The owner's computer verifies the association before allowing certain communications from the mobile device. Additionally, the SIM uses specific keys to transmit information, and the owner's computer responds by providing a second set of keys for data communication between the mobile device and the owner's computer.

Furthermore, the method outlined in the patent enables the remote provisioning of a SIM by the owner of the mobile device. This involves the SIM sending identification numbers to the MNO computer, which then reports them to the owner's computer. The owner's computer provisions application-specific security keys, which are then sent back to the MNO computer for establishing a secure communication line with the mobile device. This process can be repeated whenever new security keys are required, ensuring ongoing secure communication between the mobile device and the owner's computer. The patent also mentions the use of Universal Integrated Circuit Cards (UICC) and Universal SIMs in the system and method for enhanced security and functionality.
