A METHOD OF STATISTICAL RANDOMNESS TEST FOR KEY DERIVATION

摘要

PURPOSE: A method for evaluating the randomness of a derivation key is provided to statistically evaluate the randomness of the derivation key of a multi block output function type. CONSTITUTION: M master keys of n bits are randomly generated. N master keys are generated from the above master keys. A derivation key which encodes the auxiliary input data of n bits is outputted by using the master key of n bits. The derivation key which performs exclusive OR operation is generated.
