Mobile communications device providing secure element data wiping features and related methods

摘要

A mobile communications device may include a near field communications (NFC) device, an input device configured to generate a memory wipe command, a memory, and a memory controller coupled with the NFC device, the input device, and the memory. The memory controller may be configured to receive secure data from a provisioning server and store the secure data into the memory, receive wiping instruction data from the provisioning server and store the wiping instruction data into the memory for wiping the secure data from the memory, and wipe the secure data from the memory without an over-the-air (OTA) connection to the provisioning server based upon the memory wipe command and the wiping instruction data stored in the memory.

1. A mobile communications device comprising:
a near field communications (NFC) device; an input device configured to generate a memory wipe command; a secure element memory configured to install secure data from a trusted service manager (TSM) only during an over-the-air (OTA) secure channel connection with the TSM; and a secure element controller coupled with the NFC device, the input device, and the secure element memory, the secure element controller being configured to
establish the secure channel OTA connection with the TSM and receive secure data from the TSM to install in the secure element memory,receive wiping instruction data from the TSM during the secure channel OTA connection with the TSM for wiping the secure data from the secure element memory, andwipe the secure data from the secure element memory at a later time without a secure channel OTA connection with the TSM based upon the memory wipe command and the received wiping instruction data.
