Patent number: 11303461Abstract: 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 sources and/or minimizing a blind zone of a validity checking module. 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.Type: GrantFiled: November 8, 2019Date of Patent: April 12, 2022Inventors: Ihor Vasyltsov, Karpinskyy Bohdan, Kalesnikau Aliaksei, Yun-Hyeok Choi

Publication number: 20200145235Abstract: Systems and methods are described based on an integrated circuit that performs a challenge-response physically unclonable function (PUF). The PUF is used for challenge-response authentication. The integrated circuit includes a PUP block configured to output an n-bit internal response corresponding to a challenge that requests a response where n is an integer greater than 1 and a response generator configured to calculate a Hamming weight of the internal response and output the response by comparing the Hamming weight with at least one reference.Type: ApplicationFiled: September 11, 2019Publication date: May 7, 2020Inventors: Yunhyeok Choi, Yongki Lee, Yongsoo Kim, Jieun Park, Karpinskyy Bohdan
