Introduction This document describes the use of the Camellia block cipher algorithm in Counter (CTR) mode and Counter with CBC-MAC (CCM) 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) [5]. 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 the AES block of AES-based algorithms with a Camellia block. Camellia already has been adopted by the IETF and other international standardization organizations; in particular, the IETF has published specifications for the use of Camellia with IPsec [6], TLS [7], Secure/Multipurpose Internet Mail Extensions (S/MIME) [8], and XML Securiy [9]. Camellia is one of the three ISO/IEC international standard [10] 128-bit block ciphers (Camellia, AES, and Super Effective and Efficient Delivery (SEED)). Camellia was selected as a recommended cryptographic primitive by the EU NESSIE (New European Schemes for Signatures, Integrity and Encryption) project [11] and Kato, et al. Informational [Page 2]
RFC 5528 Camellia-CTR and Camellia-CCM algorithms April 2009 was included in the list of cryptographic techniques for Japanese e-Government systems that was selected by the Japanese CRYPTREC (Cryptography Research and Evaluation Committees) [12]. Since optimized source code is provided under several open source licenses [13], Camellia has also been adopted by several open source projects (OpenSSL, FreeBSD, Linux, and Firefox). The algorithm specification and object identifiers are described in [1]. The Camellia web site [14] contains a wealth of information about Camellia, including detailed specification, security analysis, performance figures, reference implementation, optimized implementation, test vectors (TVs), and intellectual property information. 1.1. Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [2]. All multi-octet values in this document are encoded and represented in network byte order, i.e., most significant octet first. 2. The Camellia Cipher Algorithm All symmetric block cipher algorithms share common characteristics and variables, including mode, key size, weak keys, and block size. The following sections contain descriptions of the relevant characteristics of Camellia. 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. 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 16 octets (128 bits). Kato, et al. Informational [Page 3]
RFC 5528 Camellia-CTR and Camellia-CCM algorithms April 2009 Padding is required by the algorithm to maintain a 16-octet (128-bit) block size. Padding MUST be added such that the data to be encrypted 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 Encapsulating Security Payload (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 for Camellia are available at [14]. The NESSIE project has reported on the performance of optimized implementations independently [11]. 3. Modes of Operation Camellia Counter (Camellia-CTR) mode and Camellia Counter with CBC- MAC (Camellia-CCM) mode are based on [3][15][4]. CTR mode [3] behaves like a stream cipher, but is based on a block cipher primitive (that is, CTR mode operation of a block cipher results in a stream cipher). CCM mode [15][4] is a generic authenticate-and-encrypt block cipher mode. In this specification, CCM is used with the Camellia [1] block cipher. 4. Test Vectors 4.1. Camellia-CTR This section contains nine TVs, which can be used to confirm that an implementation has correctly implemented Camellia-CTR. The first three TVs use Camellia with a 128-bit key; the next three TVs use Camellia with a 192-bit key; and the last three TVs use Camellia with a 256-bit key. Kato, et al. Informational [Page 4]
