SECURE TIME FUNCTIONALITY FOR A WIRELESS DEVICE
First Claim
1. A wireless transmit/receive unit (WTRU) for providing advanced security functions, the WTRU comprising:
- a trust platform module (TPM) for performing trusted computing operations; and
a secure time component (STC) for providing a secure measurement of a current time, wherein the STC and the TPM are integrated to provide accurate trusted time information to applications on the WTRU.

Abstract
The present invention is related to a wireless transmit/receive unit (WTRU) for providing advanced security functions. The WTRU includes trusted platform module (TPM) for performing trusted computing operations; and a secure time component (STC) for providing a secure measurement of a current time. The STC and the TPM are integrated to provide accurate trusted time information to internal and external to the WTRU. The STC may be located on an expanded a subscriber identity module (SIM), on the WTRU platform, or two STCs may be used, one in each location. Similarly, the TPM may be located on an expanded SIM, on the WTRU platform, or two TPMs may be used, one in each location. Preferably, the STC will include a real time clock (RTC); a tamper detection and power failure unit; and a time report and sync controller.
