Abstract
An apparatus and method for securing a personal identification number (PIN) on a mobile device are provided. The method may include receiving a request for the PIN from a secure element on the mobile device, instantiating a trusted user interface (TUI), collecting the PIN via the TUI, and securely transmitting the PIN from a trusted execution environment (TEE) associated with the TUI to a secure element (SE).
Claims30
A method for securing a personal identification number (PIN) on a mobile device, the method comprising:
- receiving a request for the PIN from a secure element on the mobile device;
- instantiating a trusted user interface (TUI);
- collecting the PIN via the TUI;
- and
- securely transmitting the PIN from a trusted execution environment (TEE) associated with the TUI to a secure element (SE).
An apparatus for securing a personal identification number (PIN) on a mobile device, the apparatus comprising:
- memory in a trusted execution environment (TEE) on the mobile device, the memory configured to store executable instructions for securing the PIN;
- a secure element (SE) associated with the mobile device;
- and
- a processor in the TEE on the mobile device, wherein the processor is configured to execute the stored instructions to:
- receive a request for the PIN from the secure element on the mobile device,
- instantiate a trusted user interface (TUI),
- collect the PIN via the TUI, and
- securely transmit the PIN from the TEE to the SE.
A non-transitory computer-readable storage medium storing instructions that, when executed, cause at least one processor to:
- receive a request for a personal identification number (PIN) from a secure element on a mobile device;
- instantiate a trusted user interface (TUI);
- collect the PIN via the TUI;
- and
- securely transmit the PIN from a trusted execution environment (TEE) associated with the TUI to a secure element (SE).
