  • Preventing the unwanted external detection of operations in digital integrated circuits
    Publication number: 20040143747
    Abstract: In a digital circuit comprising an asynchronous circuit, the supply voltage of the asynchronous circuit is varied by means of a random voltage jitter. The random variation of the supply voltage causes a time jitter in the processing of the individual operations within the asynchronous circuit, whereby an artificial synchronizing of individual measurements in side channel attacks is prevented.
