Abstract
Methods and systems for providing lime information in intermittently powered devices that are batteryless and operate purely on harvested energy (also referred to as zero power devices). The method of these teachings for improving security of zero power devices includes determining an estimate of time using a decay of data in a volatile device, and deciding whether to respond to a query based on the estimate of time.
