Abstract: PURPOSE: A message blinding method of RSA(Rivest Shamir Adleman) is provided to minimize the degradation of a processing speed by performing a padding elimination work. CONSTITUTION: An RSA encryption system establishes random padding r including a disjoint relation with n(S101). The RSA encryption system establishes plural additional calculation by using the random padding(S103). The RSA encryption system establishes the maximum value of a variable by using total bit numbers when the bit is displayed as a binary number(S105).

Abstract: PURPOSE: An aria encryption apparatus and a method thereof are provided to efficiently use an aria encryption algorithm by calculating the output of a masking S-box. CONSTITUTION: A controller(110) entirely controls the drive of aria encryption devices(100). The controller generates a masked random number. A round key generating section(120) generates a round key by using an inputted cryptographic key. A masking section(130) generates masked input data by using inputted data and the masked random number generated in the controller. An erasable programmable read-only memory(140) stores a table used for calculating the output of a S-box. An operational sequence generating unit(150) randomly generates an operational sequence for executing key addition. A key edition section(160) calculates an input value masked based on a generated operational sequence and a masked round key value. A S-box operation section(170) calculates the output of the S-box.
