PROBLEM TO BE SOLVED: To provide advanced security functions.SOLUTION: A wireless transmit/receive unit (WTRU) includes a reliable platform module (TPM) for performing reliable computing operations, and a secure time component (STC) for providing a secure measurement value of a current time. The STC and the TPM are integrated to provide accurate and reliable time information to the inside and outside of the WTRU. The STC may be located on an expanded subscriber identity module (SIM) or on a WTRU platform, or two STCs may be used, one in each location. Similarly, the TPM may be located on an expanded SIM or a WTRU platform, or two TPMs may be used, one in each location.SELECTED DRAWING: Figure 2 |
