Method and apparatus for hardware-assisted secure real time clock management

摘要

Embodiments of a system and method for secure clock management in a mobile device, or user equipment, are generally described herein. A timer offset may be calculated between a first secure clock time and a first network time. A reset delta based on at least the timer offset may be obtained and a recovered secure clock time based on at least the reset delta may be generated. A one-time password may be generated based on at least the recovered secure clock time.

1. An apparatus for wireless clock management, the apparatus comprising:
a timer offset calculating circuit configured to calculate a timer offset between a first secure clock time and a first network time; a reset delta obtaining circuit configured to obtain a reset delta based on at least the timer offset, the reset delta including a value that represents a time duration during which the apparatus has been inoperative; and a secure clock time generating circuit configured to generate a recovered secure clock time based on at least the reset delta.
