Abstract: A system is provided that includes a processor and a system memory coupled to the processor, the system memory stores at least one application for execution by the processor. The system also includes logic coupled to the processor, the logic providing a secure time reference. The processor selectively accesses the secure time reference to generate a virtual time reference for the at least one application.

Abstract: Systems and methods for detecting tampering of a signal are described herein. Some illustrative embodiments include an integrated circuit including an input/output (I/O) pad (electrically accessible from outside the integrated circuit), an I/O circuit coupled to the I/O pad that receives an internally generated signal and causes the internally generated signal to be propagated to the I/O pad, and a comparator having first and second input nodes (the first input node configured to receive a digital representation of the internally generated signal, and the second input node coupled to the I/O pad and configured to receive a digital representation of a signal present at the I/O pad). The comparator signals an exception condition if a logic level of a bit of the digital representation of the internally generated signal does not match a logic level of a bit of the digital representation of the signal present at the I/O pad.

Abstract: A communication device includes a keyboard with key functions and a microphone connected to the outside of the housing of the device by an acoustic path which opens to the outside of the device through one of the keys of the keyboard. The microphone is accommodated either on the inside of the key, or in another arbitrary area inside the device, while still being connected to the acoustic path by an acoustic channel.
