Abstract

An encryption device includes a controller configured to output random data including K random bits, where K is an integer greater than or equal to 2, and a random shuffling circuit configured to receive N input bits and perform a random shuffling operation on the N input bits, where N=3×2^b, and b is a non-negative integer, based on a plurality of layers each including the random data and an even number of multiplexers, to output final shuffling data having a uniform distribution, wherein a total number of multiplexers included in the random shuffling circuit is 2×K, each of the K random bits is input to two multiplexers included in one layer, and a number of layers is a smallest integer from among integers greater than or equal to K divided by a largest integer from among integers less than or equal to N/2.
