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 9):
A security device, comprising:\n a random signal generating unit comprising at least two entropy sources, and configured to generate a plurality of digitized signals; a validity detector configured to detect transition of each of the plurality of digitized signals to detect validity of each of the plurality of digitized signals by using a time-invariant characteristic of each of the plurality of digitized signals and to generate a plurality of validity signals each corresponding to each of the plurality of digitized signals; and a finalizer configured to receive the plurality of digitized signals and the plurality of validity signals and to output at least one valid digitized signal among the plurality of digitized signals, based on the plurality of validity signals.
