Secure reset of personal and service provider information on mobile devices

摘要

Systems and methods are described herein for supporting end users of a mobile device, such as a mobile phone, to reset a secure element associated with the communication device. The reset process may include clearing the secure element, associated memories, and storage devices of any user specific or personalized information associated with the user. The reset process may also include removing or resetting keys or other identifiers within the secure element that associate the mobile device with a particular secure service provider. According to various embodiments, a computer-implemented method for resetting a secure element within a network device may include receiving an encrypted reset request message at the secure element, decrypting the encrypted reset request message using a communication key, verifying authorization for the reset request message, and atomically clearing parameters associated with the secure element.

主权项

1. A computer-implemented method for resetting secure memories within computing devices configured to conduct financial transactions, comprising:
receiving an encrypted reset request message for a secure memory of a computing device configured to conduct financial transactions, the encrypted reset request message being associated with a request to change control of the secure memory from a first secure service provider to a second secure service provider, the encrypted reset request message originating from a source other than the first secure service provider; providing a communication key within the secure memory; decrypting the encrypted reset request message within the secure memory using the communication key; verifying authorization for the reset request message; and clearing parameters associated with the first secure service provider from the secure memory based on instructions provided in the verified reset request message that originated from the source other than the first secure service provider.
