GPS geo-locational (and time services provision) has been available for many years, and its reliability has been presumed for at least that long. That presumption may no longer hold. Wired magazine reports here that “[r]esearchers at Virginia Tech and Cornell University have spent more than a year building equipment that can fake GPS signals capable of fooling receivers.” What this demonstration means, of course, is that both location and time coordinates can be spoofed. If time information received can be spoofed, that opens the door to time-based data manipulation. Access (or, more correctly stated non-access) issues have always presented an issue to enterprises that need uninterrupted (or interruptible) source of trusted time. The capability to spoof time itself further strengthens the argument in favor of a local trusted time source.
