Abstract:
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.

Claim (Index 17):
The security device of  claim 9 ,\n wherein the validity detector comprises at least two detectors each configured to detect transition of one of the plurality of digitized signals, and at least two valid signal generators each configured to generate a validity signal, wherein the at least two detectors each comprises: an OR gate configured to receive one of the plurality of digitized signals and output first data; an AND gate configured to receive one of the plurality of digitized signals and output second data; a fourth storage unit configured to receive an inverting signal of a reset signal as a clock signal and to output one of the plurality of digitized signals ; and a third multiplexer configured to receive the first data and the second data and to output third data to the valid signal generator, based on one of the plurality of digitized signals; and wherein the at least two valid signal generators each comprises a NOR gate configured to output a validity signal based on the third data and the reset signal.
