1.  Introduction

1.1.  ARIA Overview

   ARIA is a general-purpose block cipher algorithm developed by Korean
   cryptographers in 2003.  It is an iterated block cipher with 128-,
   192-, and 256-bit keys and encrypts 128-bit blocks in 12, 14, and 16
   rounds, depending on the key size.  It is secure and suitable for
   most software and hardware implementations on 32-bit and 8-bit
   processors.  It was established as a Korean standard block cipher
   algorithm in 2004 [ARIAKS] and has been widely used in Korea,
   especially for government-to-public services.  It was included in
   PKCS #11 in 2007 [ARIAPKCS].

2.  Algorithm Description

   The algorithm consists of a key scheduling part and data randomizing
   part.

2.1.  Notations

   The following notations are used in this document to describe the
   algorithm.

      ^   bitwise XOR operation
      <<< left circular rotation
      >>> right circular rotation
      ||  concatenation of bit strings
      0x  hexadecimal representation

2.2.  Key Scheduling Part

   Let K denote a master key of 128, 192, or 256 bits.  Given the master
   key K, we first define 128-bit values KL and KR as follows.

   KL || KR = K || 0 ... 0,

   where the number of zeros is 128, 64, or 0, depending on the size of
   K.  That is, KL is set to the leftmost 128 bits of K and KR is set to
   the remaining bits of K (if any), right-padded with zeros to a
   128-bit value.  Then, we define four 128-bit values (W0, W1, W2, and
   W3) as the intermediate round values appearing in the encryption of
   KL || KR by a 3-round, 256-bit Feistel cipher.

   W0 = KL,
   W1 = FO(W0, CK1) ^ KR,
   W2 = FE(W1, CK2) ^ W0,
   W3 = FO(W2, CK3) ^ W1.

   Here, FO and FE, respectively called odd and even round functions,
   are defined in Section 2.4.1.  CK1, CK2, and CK3 are 128-bit
   constants, taking one of the following values.

   C1 =  0x517cc1b727220a94fe13abe8fa9a6ee0
   C2 =  0x6db14acc9e21c820ff28b1d5ef5de2b0
   C3 =  0xdb92371d2126e9700324977504e8c90e

   These values are obtained from the first 128*3 bits of the fractional
   part of 1/PI, where PI is the circle ratio.  Now the constants CK1,
   CK2, and CK3 are defined by the following table.

       Key size  CK1  CK2  CK3
         128     C1   C2   C3
         192     C2   C3   C1
         256     C3   C1   C2

   For example, if the key size is 192 bits, CK1 = C2, CK2 = C3, and
   CK3 = C1.

   Once W0, W1, W2, and W3 are determined, we compute encryption round
   keys ek1, ..., ek17 as follows.

   ek1  = W0 ^(W1 >>> 19),
   ek2  = W1 ^(W2 >>> 19),
   ek3  = W2 ^(W3 >>> 19),
   ek4  = (W0 >>> 19) ^ W3,
   ek5  = W0 ^ (W1 >>> 31),
   ek6  = W1 ^ (W2 >>> 31),
   ek7  = W2 ^ (W3 >>> 31),
   ek8  = (W0 >>> 31) ^ W3,
   ek9  = W0 ^ (W1 <<< 61),
   ek10 = W1 ^ (W2 <<< 61),
   ek11 = W2 ^ (W3 <<< 61),
   ek12 = (W0 <<< 61) ^ W3,
   ek13 = W0 ^ (W1 <<< 31),
   ek14 = W1 ^ (W2 <<< 31),
   ek15 = W2 ^ (W3 <<< 31),
   ek16 = (W0 <<< 31) ^ W3,
   ek17 = W0 ^ (W1 <<< 19).

   The number of rounds depends on the size of the master key as
   follows.

        Key size     Number of Rounds
         128              12
         192              14
         256              16

   Due to an extra key addition layer in the last round, 12-, 14-, and
   16-round algorithms require 13, 15, and 17 round keys, respectively.

   Decryption round keys are derived from the encryption round keys.

   dk1 = ek{n+1},
   dk2 = A(ek{n}),
   dk3 = A(ek{n-1}),
   ...,
   dk{n}= A(ek2),
   dk{n+1}= ek1.

   Here, A and n denote the diffusion layer of ARIA and the number of
   rounds, respectively.  The diffusion layer A is defined in Section
   2.4.3.

2.3.  Data Randomizing Part

   The data randomizing part of the ARIA algorithm consists of the
   encryption and decryption processes.  The encryption and decryption
   processes use functions FO, FE, A, SL1, and SL2.  These functions are
   defined in Section 2.4.

2.3.1.  Encryption Process

2.3.1.1.  Encryption for 128-Bit Keys

   Let P be a 128-bit plaintext and K be a 128-bit master key.  Let ek1,
   ..., ek13 be the encryption round keys defined by K.  Then the
   ciphertext C is computed by the following algorithm.

   P1  = FO(P  , ek1 );              // Round 1
   P2  = FE(P1 , ek2 );              // Round 2
   P3  = FO(P2 , ek3 );              // Round 3
   P4  = FE(P3 , ek4 );              // Round 4
   P5  = FO(P4 , ek5 );              // Round 5
   P6  = FE(P5 , ek6 );              // Round 6
   P7  = FO(P6 , ek7 );              // Round 7
   P8  = FE(P7 , ek8 );              // Round 8
   P9  = FO(P8 , ek9 );              // Round 9
   P10 = FE(P9 , ek10);              // Round 10
   P11 = FO(P10, ek11);              // Round 11
   C   = SL2(P11 ^ ek12) ^ ek13;     // Round 12

2.3.1.2.  Encryption for 192-Bit Keys

   Let P be a 128-bit plaintext and K be a 192-bit master key.  Let ek1,
   ..., ek15 be the encryption round keys defined by K.  Then the
   ciphertext C is computed by the following algorithm.

   P1  = FO(P  , ek1 );              // Round 1
   P2  = FE(P1 , ek2 );              // Round 2
   P3  = FO(P2 , ek3 );              // Round 3
   P4  = FE(P3 , ek4 );              // Round 4
   P5  = FO(P4 , ek5 );              // Round 5
   P6  = FE(P5 , ek6 );              // Round 6
   P7  = FO(P6 , ek7 );              // Round 7
   P8  = FE(P7 , ek8 );              // Round 8
   P9  = FO(P8 , ek9 );              // Round 9
   P10 = FE(P9 , ek10);              // Round 10
   P11 = FO(P10, ek11);              // Round 11
   P12 = FE(P11, ek12);              // Round 12
   P13 = FO(P12, ek13);              // Round 13
   C   = SL2(P13 ^ ek14) ^ ek15;     // Round 14

2.3.1.3.  Encryption for 256-Bit Keys

   Let P be a 128-bit plaintext and K be a 256-bit master key.  Let ek1,
   ..., ek17 be the encryption round keys defined by K.  Then the
   ciphertext C is computed by the following algorithm.

   P1 = FO(P  , ek1 );              // Round 1
   P2 = FE(P1 , ek2 );              // Round 2
   P3 = FO(P2 , ek3 );              // Round 3
   P4 = FE(P3 , ek4 );              // Round 4
   P5 = FO(P4 , ek5 );              // Round 5
   P6 = FE(P5 , ek6 );              // Round 6
   P7 = FO(P6 , ek7 );              // Round 7
   P8 = FE(P7 , ek8 );              // Round 8
   P9 = FO(P8 , ek9 );              // Round 9
   P10= FE(P9 , ek10);              // Round 10
   P11= FO(P10, ek11);              // Round 11
   P12= FE(P11, ek12);              // Round 12
   P13= FO(P12, ek13);              // Round 13
   P14= FE(P13, ek14);              // Round 14
   P15= FO(P14, ek15);              // Round 15
   C  = SL2(P15 ^ ek16) ^ ek17;     // Round 16

2.3.2.  Decryption Process

   The decryption process of ARIA is the same as the encryption process
   except that encryption round keys are replaced by decryption round
   keys.  For example, encryption round keys ek1, ..., ek13 of the
   12-round ARIA algorithm are replaced by decryption round keys dk1,
   ..., dk13, respectively.

2.4.  Components of ARIA

2.4.1.  Round Functions

   There are two types of round functions for ARIA.  One is called an
   odd round function and is denoted by FO.  It takes as input a pair
   (D,RK) of two 128-bit strings and outputs

   FO(D,RK) = A(SL1(D ^ RK)).

   The other is called an even round function and is denoted by FE.  It
   takes as input a pair (D,RK) of two 128-bit strings and outputs

   FE(D,RK) = A(SL2(D ^ RK)).

   Functions SL1 and SL2, called substitution layers, are described in
   Section 2.4.2.  Function A, called a diffusion layer, is described in
   Section 2.4.3.

2.4.2.  Substitution Layers

   ARIA has two types of substitution layers that alternate between
   rounds.  Type 1 is used in the odd rounds, and type 2 is used in the
   even rounds.

   Type 1 substitution layer SL1 is an algorithm that takes a 16-byte
   string x0 || x1 ||...|| x15 as input and outputs a 16-byte string
   y0 || y1 ||...|| y15 as follows.

   y0 = SB1(x0),  y1 = SB2(x1),  y2 = SB3(x2),  y3 = SB4(x3),
   y4 = SB1(x4),  y5 = SB2(x5),  y6 = SB3(x6),  y7 = SB4(x7),
   y8 = SB1(x8),  y9 = SB2(x9),  y10= SB3(x10), y11= SB4(x11),
   y12= SB1(x12), y13= SB2(x13), y14= SB3(x14), y15= SB4(x15).

   Type 2 substitution layer SL2 is an algorithm that takes a 16-byte
   string x0 || x1 ||...|| x15 as input and outputs a 16-byte string
   y0 || y1 ||...|| y15 as follows.

   y0 = SB3(x0),  y1 = SB4(x1),  y2 = SB1(x2),  y3 = SB2(x3),
   y4 = SB3(x4),  y5 = SB4(x5),  y6 = SB1(x6),  y7 = SB2(x7),
   y8 = SB3(x8),  y9 = SB4(x9),  y10= SB1(x10), y11= SB2(x11),
   y12= SB3(x12), y13= SB4(x13), y14= SB1(x14), y15= SB2(x15).

   Here, SB1, SB2, SB3, and SB4 are S-boxes that take an 8-bit string as
   input and output an 8-bit string.  These S-boxes are defined by the
   following look-up tables.

   For example, SB1(0x23) = 0x26 and SB4(0xef) = 0xd3.  Note that SB3
   and SB4 are the inverse functions of SB1 and SB2, respectively, and
   accordingly SL2 is the inverse of SL1.

2.4.3.  Diffusion Layer

   Diffusion layer A is an algorithm that takes a 16-byte string x0 ||
   x1 || ... || x15 as input and outputs a 16-byte string
   y0 || y1 ||...|| y15 by the following equations.

      y0  = x3 ^ x4 ^ x6 ^ x8  ^ x9  ^ x13 ^ x14,
      y1  = x2 ^ x5 ^ x7 ^ x8  ^ x9  ^ x12 ^ x15,
      y2  = x1 ^ x4 ^ x6 ^ x10 ^ x11 ^ x12 ^ x15,
      y3  = x0 ^ x5 ^ x7 ^ x10 ^ x11 ^ x13 ^ x14,
      y4  = x0 ^ x2 ^ x5 ^ x8  ^ x11 ^ x14 ^ x15,
      y5  = x1 ^ x3 ^ x4 ^ x9  ^ x10 ^ x14 ^ x15,
      y6  = x0 ^ x2 ^ x7 ^ x9  ^ x10 ^ x12 ^ x13,
      y7  = x1 ^ x3 ^ x6 ^ x8  ^ x11 ^ x12 ^ x13,
      y8  = x0 ^ x1 ^ x4 ^ x7  ^ x10 ^ x13 ^ x15,
      y9  = x0 ^ x1 ^ x5 ^ x6  ^ x11 ^ x12 ^ x14,
      y10 = x2 ^ x3 ^ x5 ^ x6  ^ x8  ^ x13 ^ x15,
      y11 = x2 ^ x3 ^ x4 ^ x7  ^ x9  ^ x12 ^ x14,
      y12 = x1 ^ x2 ^ x6 ^ x7  ^ x9  ^ x11 ^ x12,
      y13 = x0 ^ x3 ^ x6 ^ x7  ^ x8  ^ x10 ^ x13,
      y14 = x0 ^ x3 ^ x4 ^ x5  ^ x9  ^ x11 ^ x14,
      y15 = x1 ^ x2 ^ x4 ^ x5  ^ x8  ^ x10 ^ x15.

   Note that A is an involution.  That is, for any 16-byte input string
   x, x = A(A(x)) holds.

3.  Security Considerations

   ARIA is designed to be resistant to all known attacks on block
   ciphers [ARIA03].  Its security was analyzed by the COSIC group of
   K.U.Leuven in Belgium [ARIAEVAL] and no security flaw has been found.
