摘要： 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.

摘要： A security device generates a key based on a physically unclonable function (PUF). The security device includes a physically unclonable function (PUF) block, an integrity detector, and a post processor. The PUF block outputs a plurality of first random signals and a plurality of corresponding first inverted random signals each having a logic level opposite to that of each of the plurality of corresponding first random signals. The integrity detector determines data integrity of the plurality of first random signals by using the plurality of first random signals and the plurality of corresponding first inverted random signals. The post processor generates a first row key that includes validity signals satisfying the data integrity.
