Abstract
There is provided a high-speed pipelined ARIA encryption apparatus. The high-speed pipelined ARIA encryption apparatus includes a round key generator for generating a plurality of round keys required for performing an encryption operation using a master key formed to have uniform bits, a plurality of round units whose number is in proportion to the number of times of round operations corresponding to the number of bit of an input value to receive the round keys and the input value and to perform the round operations, and a plurality of pipelined register provided between the round units to transmit the output value of a previous round unit as the input value of the next round unit. A plurality of round units are provided and pipelined registers are inserted between the round units so that it is possible to improve the performance of processing a large amount of data and to perform ARIA encryption at high speed.
