Internet-Draft  Camellia-CTR and Camellia-CCM algorithms   November 2007


1.  Introduction

   This document describes the use of the Camellia block cipher
   algorithm in Counter mode and Counter with CBC-MAC Mode.

   Camellia is a symmetric cipher with a Feistel structure.  Camellia
   was developed jointly by NTT and Mitsubishi Electric Corporation in
   2000.  It was designed to withstand all known cryptanalytic attacks,
   and it has been scrutinized by worldwide cryptographic experts.
   Camellia is suitable for implementation in software and hardware,
   offering encryption speed in software and hardware implementations
   that is comparable to Advanced Encryption Standard (AES) [10].

   Camellia supports 128-bit block size and 128-, 192-, and 256-bit key
   lengths, i.e., the same interface specifications as the AES.
   Therefore, it is easy to implement Camellia based algorithms by
   replacing AES block of AES based algorithms to Camellia block.

   Camellia is adopted as IETF and several international standardization
   organizations.  Camellia is already adopted as IPSec [7], TLS [6],
   S/MIME [4] and XML [5].  Camellia is adopted for the one of three
   ISO/IEC international standard cipher [13] as 128bit block
   cipher(Camellia AES and SEED).  Camellia was selected as a
   recommended cryptographic primitive by the EU NESSIE (New European
   Schemes for Signatures, Integrity and Encryption) project [11] and
   was included in the list of cryptographic techniques for Japanese
   e-Government systems that was selected by the Japan CRYPTREC
   (Cryptography Research and Evaluation Committees) [12].

   Since optimized source code is provided by several open source
   lisences [14], Camellia is also adopted by several open source
   projects.  Camellia is already adopted by Openssl.  Additional API
   for Network Security Services (NSS) and IPsec stack of Linux and Free
   BSD are prepared or working progress for release.

   The algorithm specification and object identifiers are described in
   [2].  The Camellia homepage [15] contains a wealth of information
   about Camellia, including detailed specification, security analysis,
   performance figures, reference implementation, optimized
   implementation, test vectors, and intellectual property information.

2.  The Camellia Cipher Algorithm

   All symmetric block cipher algorithms share common characteristics
   and variables, including mode, key size, weak keys, block size, and
   rounds.  The following sections contain descriptions of the relevant
   characteristics of Camellia.

   The algorithm specification and object identifiers are described in
   [2].

2.1.  Key Size

   Camellia supports three key sizes: 128 bits, 192 bits, and 256 bits.
   The default key size is 128 bits, and all implementations MUST
   support this key size.  Implementations MAY also support key sizes of
   192 bits and 256 bits.

   Camellia uses a different number of rounds for each of the defined
   key sizes.  When a 128-bit key is used, implementations MUST use 18
   rounds.  When a 192-bit key is used, implementations MUST use 24
   rounds.  When a 256-bit key is used, implementations MUST use 24
   rounds.

2.2.  Weak Keys

   At the time of writing this document there are no known weak keys for
   Camellia.

2.3.  Block Size and Padding

   Camellia uses a block size of sixteen octets (128 bits).

   Padding is required by the algorithms to maintain a 16-octet (128-
   bit) block size.  Padding MUST be added such that the data to be
   encrypted (which includes the ESP Pad Length and Next Header fields)
   has a length that is a multiple of 16 octets.

   Because of the algorithm specific padding requirement, no additional
   padding is required to ensure that the ciphertext terminates on a
   4-octet boundary (i.e. maintaining a 16-octet block size guarantees
   that the ESP Pad Length and Next Header fields will be right aligned
   within a 4-octet word).  Additional padding MAY be included as long
   as the 16-octet block size is maintained.

2.4.  Performance

   Performance figures of Camellia are available at
   <http://info.isl.ntt.co.jp/crypt/camellia/>.  NESSIE project has

3.  Modes of Operation

   Camellia Counter mode (Camellia-CTR) and Camellia Counter with CBC-
   MAC (Camellia-CCM) are discussed in this specification.

   Counter mode [8] behave like stream ciphers, but are constructed
   based on a block cipher primitive (that is, counter mode operation of
   a block cipher results in a stream cipher.)

   CCM mode is a generic authenticate-and-encrypt block cipher mode [3].
   In this specification, CCM is used with the Camellia [2] block
   cipher.

3.1.  Counter

3.1.1.  Definitions

   Camellia(K, X)
             Output of the Camellia encryption algorithm under the fresh
             key K applied to the data block X.

   N         Nonce.

   PT[n]     n-th plain text block splited by 128-bit unit.

   X || Y    Concatenation of two octet strings X and Y.

   X XOR Y   Bitwise exclusive-OR of two octet strings X and Y of the
             same length.

3.1.2.  Camellia-CTR

   Camellia-CTR requires the encryptor to generate a unique per-packet
   value, and communicate this value to the decryptor.  This
   specification calls this per-packet value an initialization vector
   (IV).  The same IV and key combination MUST NOT be used more than
   once.  The encryptor can generate the IV in any manner that ensures
   uniqueness.  Common approaches to IV generation include incrementing
   a counter for each packet and linear feedback shift registers
   (LFSRs).

   This specification calls for the use of a nonce for additional
   protection against precomputation attacks.  The nonce value need not
   be secret.  However, the nonce MUST be unpredictable prior to the
   establishment of the IPsec security association that is making use of
   Camellia-CTR.

   Camellia-CTR has many properties that make it an attractive

Internet-Draft  Camellia-CTR and Camellia-CCM algorithms   November 2007


   encryption algorithm for in high-speed networking.  Camellia-CTR uses
   the Camellia block cipher to create a stream cipher.  Data is
   encrypted and decrypted by XORing with the key stream produced by
   Camellia encrypting sequential counter block values.  Camellia-CTR is
   easy to implement, and Camellia-CTR can be pipelined and
   parallelized.  Camellia-CTR also supports key stream precomputation.

   Pipelining is possible because Camellia has multiple rounds (see
   Section 2.).  A hardware implementation (and some software
   implementations) can create a pipeline by unwinding the loop implied
   by this round structure.  For example, after a 16-octet block has
   been input, one round later another 16-octet block can be input, and
   so on.  In Camellia-CTR, these inputs are the sequential counter
   block values used to generate the key stream.

   Multiple independent Camellia encrypt implementations can also be
   used to improve performance.  For example, one could use two Camellia
   encrypt implementations in parallel, to process a sequence of counter
   block values, doubling the effective throughput.

   The sender can precompute the key stream.  Since the key stream does
   not depend on any data in the packet, the key stream can be
   precomputed once the nonce and IV are assigned.  This precomputation
   can reduce packet latency.  The receiver cannot perform similar
   precomputation because the IV will not be known before the packet
   arrives.

   When used correctly, Camellia-CTR provides a high level of
   confidentiality.  Unfortunately, Camellia-CTR is easy to use
   incorrectly.  Being a stream cipher, any reuse of the per-packet
   value, called the IV, with the same nonce and key is catastrophic.
   An IV collision immediately leaks information about the plaintext in
   both packets.  For this reason, it is inappropriate to use this mode
   of operation with static keys.  Extraordinary measures would be
   needed to prevent reuse of an IV value with the static key across
   power cycles.  To be safe, implementations MUST use fresh keys with
   Camellia-CTR.

   With Camellia-CTR, it is trivial to use a valid ciphertext to forge
   other (valid to the decryptor) ciphertexts.  Thus, it is equally
   catastrophic to use Camellia-CTR without a companion authentication
   function.  Implementations MUST use Camellia-CCM such case.

   To encrypt a payload with Camellia-CTR, the encryptor partitions the
   plaintext, PT, into 128-bit blocks.  The final block need not be 128
   bits; it can be less.

         PT = PT[1] PT[2] ... PT[n]

Internet-Draft  Camellia-CTR and Camellia-CCM algorithms   November 2007


   Each PT block is XORed with a block of the key stream to generate the
   ciphertext, CT.  The Camellia encryption of each counter block
   results in 128 bits of key stream.  The most significant 96 bits of
   the counter block are set to the nonce value, which is 32 bits,
   followed by the per-packet IV value, which is 64 bits.  The least
   significant 32 bits of the counter block are initially set to one.
   This counter value is incremented by one to generate subsequent
   counter blocks, each resulting in another 128 bits of key stream.
   The encryption of n plaintext blocks can be summarized as:

         CTRBLK := N || IV || ONE
         FOR i := 1 to n-1 DO
           CT[i] := PT[i] XOR Camellia(K, CTRBLK)
           CTRBLK := CTRBLK + 1
         END
         CT[n] := PT[n] XOR TRUNC(Camellia(K, CTRBLK))

   The TRUNC() function truncates the output of the Camellia encrypt
   operation to the same length as the final plaintext block, returning
   the most significant bits.

   Decryption is similar.  The decryption of n ciphertext blocks can be
   summarized as:


         CTRBLK := N || IV || ONE
         FOR i := 1 to n-1 DO
           PT[i] := CT[i] XOR Camellia(K, CTRBLK)
           CTRBLK := CTRBLK + 1
         END
         PT[n] := CT[n] XOR TRUNC(Camellia(K, CTRBLK))

   M'        3bit number calculated by (M-2)/2.

   L         Number of octets in length field.  Valid values are from 2

             length of N.

   m         Message to authenticate and encrypt. l(m) < 2^(8*L).

   AAD       Additional authenticated data. 0 =< AAD < 2^64.

3.2.2.  Two main parameters

   For the generic CCM mode there are two parameter choices.  The first
   choice is M, the size of the authentication field.  The choice of the
   value for M involves a trade-off between message expansion and the
   probability that an attacker can undetectably modify a message.
   Valid values are 4, 6, 8, 10, 12, 14, and 16 octets.  The second
   choice is L, the size of the length field.  This value requires a
   trade-off between the maximum message size and the size of the Nonce.
   Different applications require different trade-offs, so L is a
   parameter.  Valid values of L range between 2 octets and 8 octets
   (the value L=1 is reserved).

        Name  Description                               Size    Encoding
        ----  ----------------------------------------  ------  --------
        M     Number of octets in authentication field  3 bits  (M-2)/2
        L     Number of octets in length field          3 bits  L-1

3.2.3.  Inputs

   To authenticate and encrypt a message the following information is
   required:

   1.   An encryption key K suitable for the block cipher.

   2.   A nonce N of 15-L octets.  Within the scope of any encryption
        key K, the nonce value MUST be unique.  That is, the set of
        nonce values used with any given key MUST NOT contain any
        duplicate values.  Using the same nonce for two different
        messages encrypted with the same key destroys the security
        properties of this mode.

   3.   The message m, consisting of a string of l(m) octets where 0 <=
        l(m) < 2^(8*L).  The length restriction ensures that l(m) can be
        encoded in a field of L octets.

   4.   The additional authenticated data AAD where 0 <= AAD < 2^64.
        This additional data is authenticated but not encrypted, and is

        not included in the output of this mode.  It can be used to
        authenticate plaintext packet headers, or contextual information
        that affects the interpretation of the message.  Users who do
        not wish to authenticate additional data can provide a string of
        length zero.

   The inputs are summarized as:

      Name  Description                          Size
      ----  -----------------------------------  -----------------------
      K     Block cipher key                     Depends on block cipher
      N     Nonce                                15-L octets
      m     Message to authenticate and encrypt  l(m) octets
      AAD   Additional authenticated data        0 =< AAD  < 2^64

3.2.4.  Authentication

   The first step is to compute the authentication field T. This is done
   using CBC-MAC [9].  We first define a sequence of blocks B_0, B_1,
   ..., B_n and then apply CBC-MAC to these blocks.

   The first block B_0 is formatted as follows, where l(m) is encoded in
   most-significant-byte first order:

         Octet Number   Contents
         ------------   ---------
         0              Flags
         1 ... 15-L     Nonce N
         16-L ... 15    l(m)

   Within the first block B_0, the Flags field is formatted as follows:

         Bit Number   Contents
         ----------   ----------------------
         7            Reserved (always zero)
         6            Adata
         5 ... 3      M'
         2 ... 0      L'

   Another way say the same thing is: Flags = 64*Adata + 8*M' + L'.

   The Reserved bit is reserved for future expansions and should always
   be set to zero.  The Adata bit is set to zero if AAD = 0, and set to
   one if AAD > 0.  The M' field is set to (M-2)/2.  As M can take on
   the even values from 4 to 16, the 3-bit M' field can take on the
   values from one to seven.  The 3-bit field MUST NOT have a value of
   zero, which would correspond to a 16-bit integrity check value.  The
   L' field encodes the size of the length field used to store l(m).

Internet-Draft  Camellia-CTR and Camellia-CCM algorithms   November 2007


   The parameter L can take on the values from 2 to 8 (recall, the value
   L=1 is reserved).  This value is encoded in the 3-bit L' field using
   the values from one to seven by choosing L' = L-1 (the zero value is
   reserved).

   If AAD > 0 (as indicated by the Adata field), then one or more blocks
   of authentication data are added.  These blocks contain AAD and a
   encoded in a reversible manner.  We first construct a string that
   encodes AAD.

   If 0 < AAD < (2^16 - 2^8), then the length field is encoded as two
   octets which contain the value AAD in most-significant-byte first
   order.

   If (2^16 - 2^8) <= AAD < 2^32, then the length field is encoded as
   six octets consisting of the octets 0xff, 0xfe, and four octets
   encoding AAD in most-significant-byte-first order.

   If 2^32 <= AAD < 2^64, then the length field is encoded as ten octets
   consisting of the octets 0xff, 0xff, and eight octets encoding AAD in
   most-significant-byte-first order.

   The length encoding conventions are summarized in the following
   table.  Note that all fields are interpreted in most-significant-byte
   first order.

    First two octets   Followed by       Comment
    -----------------  ----------------  -------------------------------

    0xFF00 ... 0xFFFD  Nothing           Reserved
    0xFFFE             4 octets of AAD   For (2^16 - 2^8) <= AAD < 2^32
    0xFFFF             8 octets of AAD   For 2^32 <= AAD < 2^64

   The blocks encoding a are formed by concatenating this string that
   encodes AAD with a itself, and splitting the result into 16-octet
   blocks, and then padding the last block with zeroes if necessary.
   These blocks are appended to the first block B0.

   After the (optional) additional authentication blocks have been
   added, we add the message blocks.  The message blocks are formed by
   splitting the message m into 16-octet blocks, and then padding the
   last block with zeroes if necessary.  If the message m consists of
   the empty string, then no blocks are added in this step.

   The result is a sequence of blocks B0, B1, ..., Bn.  The CBC-MAC is
   computed by:

         X_1 := Camellia( K, B_0 )
         X_i+1 := Camellia( K, X_i XOR B_i )  for i=1, ..., n
         T := first-M-bytes( X_n+1 )

   where T is the MAC value.  Note that the last block B_n is XORed with
   X_n, and the result is encrypted with the block cipher.  If needed,
   the ciphertext is truncated to give T.

3.2.5.  Encryption

   To encrypt the message data we use Counter (CTR) mode.  We first
   define the key stream blocks by:

         S_i := Camellia( K, A_i )   for i=0, 1, 2, ...

   The values A_i are formatted as follows, where the Counter field i is
   encoded in most-significant-byte first order:

         Octet Number   Contents
         ------------   ---------
         0              Flags
         1 ... 15-L     Nonce N
         16-L ... 15    Counter i

   The Flags field is formatted as follows:

         Bit Number   Contents
         ----------   ----------------------
         7            Reserved (always zero)
         6            Reserved (always zero)
         5 ... 3      Zero
         2 ... 0      L'

   Another way say the same thing is: Flags = L'.

   The Reserved bits are reserved for future expansions and MUST be set
   to zero.  Bit 6 corresponds to the Adata bit in the B_0 block, but as
   this bit is not used here, it is reserved and MUST be set to zero.
   Bits 3, 4, and 5 are also set to zero, ensuring that all the A blocks
   are distinct from B_0, which has the non-zero encoding of M in this
   position.  Bits 0, 1, and 2 contain L', using the same encoding as in
   B_0.

   The message is encrypted by XORing the octets of message m with the
   first l(m) octets of the concatenation of S_1, S_2, S_3, ... .  Note
   that S_0 is not used to encrypt the message.

   The authentication value U is computed by encrypting T with the key

   stream block S_0 and truncating it to the desired length.

         U := T XOR first-M-bytes( S_0 )

3.2.6.  Output

   The final result c consists of the encrypted message followed by the
   encrypted authentication value U.

3.2.7.  Decryption and Authentication Checking

   To decrypt a message the following information is required:

   1.   The encryption key K.

   2.   The nonce N.

   3.   The additional authenticated data AAD.

   4.   The encrypted and authenticated message c.

   Decryption starts by recomputing the key stream to recover the
   message m and the MAC value T. The message and additional
   authentication data is then used to recompute the CBC-MAC value and
   check T.

   If the T value is not correct, the receiver MUST NOT reveal any
   information except for the fact that T is incorrect.  The receiver
   MUST NOT reveal the decrypted message, the value T, or any other
   information.

4.  Test Vectors

4.1.  Camellia-CTR

   This section contains nine test vectors(TV), which can be used to
   confirm that an implementation has correctly implemented Camellia-
   CTR.  The first three test vectors use Camellia with a 128 bit key;
   the next three test vectors use Camellia with a 192 bit key; and the
   last three test vectors use Camellia with a 256 bit key.

4.2.  Camellia-CCM

   This section contains twenty four test vectors, which can be used to
   confirm that an implementation has correctly implemented Camellia-
   CCM.  In each of these test vectors, the least significant sixteen
   bits of the counter block is used for the block counter, and the
   nonce is 13 octets.  Some of the test vectors include a eight octet
   authentication value, and others include a ten octet authentication
   value.

Internet-Draft  Camellia-CTR and Camellia-CCM algorithms   November 2007


5.  Security Considerations

   Camellia-CTR and Camellia-CCM employs counter (CTR) mode for
   confidentiality.  If a counter value is ever used for more that one
   packet with the same key, then the same key stream will be used to
   encrypt both packets, and the confidentiality guarantees are voided.

   What happens if the encryptor XORs the same key stream with two
   different packet plaintexts?  Suppose two packets are defined by two
   plaintext byte sequences P1, P2, P3 and Q1, Q2, Q3, then both are
   encrypted with key stream K1, K2, K3.  The two corresponding
   ciphertexts are:

         (P1 XOR K1), (P2 XOR K2), (P3 XOR K3)

         (Q1 XOR K1), (Q2 XOR K2), (Q3 XOR K3)


   If both of these two ciphertext streams are exposed to an attacker,
   then a catastrophic failure of confidentiality results, because:

         (P1 XOR K1) XOR (Q1 XOR K1) = P1 XOR Q1
         (P2 XOR K2) XOR (Q2 XOR K2) = P2 XOR Q2
         (P3 XOR K3) XOR (Q3 XOR K3) = P3 XOR Q3

   Once the attacker obtains the two plaintexts XORed together, it is
   relatively straightforward to separate them.  Thus, using any stream
   cipher, including Camellia-CTR, to encrypt two plaintexts under the
   same key stream leaks the plaintext.
