The CAC may comprise a compression component, such as a logic gate, to compress a candidate clock signal that is to be authenticated against a reference clock signal. The CAC may further comprise a digital-to-analog converter (DAC) that may be connected to an analog-to-digital converter (ADC) of the CAC. An ADC output sequence may be generated when a predetermined input sequence is input to the DAC while the DAC and the ADC are driven by the compressed candidate clock signal. The candidate clock signal may be authenticated based on an error measurement between the ADC output sequence and a reference ADC output sequence."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Clock authentication circuitry for clock signals","description":"Embodiments of clock authentication circuitry (CAC) are generally described herein.
