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 6):
The security device of  claim 1 ,\n wherein the first combination unit is configured to receive a plurality of analog random signals including the first analog random signal and the second analog random signal, and comprises: a plurality of multiplexers configured to transmit an analog random signal among the plurality of the analog random signal to an output port in response to at least one of first selection signals; and a demultiplexer configured to receive the analog random signal from the output port and to transmit the analog random signal to the first digitizer or the second digitizer in response to a second selection signal.
