Abstract
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.
