Abstract
An electronic device for checking a randomness of an identification key device, a random key checker circuit for an electronic device and a method of checking randomness for an electronic device. An electronic device for checking a randomness of an identification key device includes an identification key generator, configured to generate an identification key. A random key checker circuit, configured to receive the identification key from the identification key generator, calculates a randomness value of the identification key according to the identification key for checking a randomness of the identification key and generates an output of the identification key with high randomness.
