Embodiments of the disclosed technologies include processing circuitry configured to perform numerous operations. The operations can include receiving a challenge continuous pulse signal, and generating a response continuous pulse signal by iteratively extending the challenge continuous pulse signal in time-domain. In some configurations, the iteratively extending includes generating a next continuous pulse signal by operating on a prior continuous pulse signal according to a stretching function, and generating a second next continuous pulse width signal by operating on the next continuous pulse signal according to a folding function."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Physically unclonable functions using pulse width chaotic maps","description":"Technologies are provided for clockless physically unclonable functions (PUFs) in reconfigurable devices.
