The security device uses an asynchronous configuration to minimize a blind zone. In various embodiments of the inventive concept, the blind zone is generated only in a period when a reset signal is at a first logic level. Therefore, it is possible to minimize the blind zone by minimizing a period in which the reset signal is at such logic level. A semiconductor device, semiconductor package, and/or smart card can be provided with such security device, as well as a method for determining a validity of a random signal using a semiconductor security device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Security device having physical unclonable function","description":"The inventive concept provides a security device capable of reducing an area of a die required for implementation of a stable PUF by increasing the value of entropy from a predefined number of entropy","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11303461","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
