W.Ehrhardt: Crypto

Cryptographic algorithms

  • In most cases encryption should be used together with authentication and decryption with verification.
    Most of the block ciphers have the EAX mode, and the HMAC
    construction can be used with both cipher types;
    see also Poly1305.
  • The secret keys should be produced by

    key derivation functions
    from pass phrases and (session) salts.

  • See the FCA demo for a basic implementation.

  • Anubis
    (designed by Vincent Rijmen and Paulo Barreto) is a 128-bit block cipher that
    uses keys of length 128 to 320 bits in steps of 32 bits. Anubis was
    a NESSIE submission which was not included in the final portfolio. My Pascal
    source implements the so called tweaked version with a recursive structured
    S-box.

  • Camellia
    is a Feistel block cipher developed jointly by NTT (Nippon Telegraph and Telephone) and Mitsubishi. It uses 128-bit input/output data
    blocks and 128, 192, or 256 bit keys. Camellia is a recommended block cipher of the
    NESSIE portfolio,
    included in ISO/IEC 18033-3, and also described in
    RFC 3713.
    The Feistel code and the S-Boxes are now 32 bit oriented, the encryption / decryption
    loops are unrolled, and the speed was increased (factors: 2.4 .. 2.9 for 32 bit and 1.2 .. 1.4 for 16 bit compilers).

  • Serpent
    (designed by Ross Anderson, Eli Biham, and Lars Knudsen) was one of
    the AES finalists; it is a 128-bit block cipher with key sizes of 128, 192, or 256 bits.
    Please note that although my code supports OMAC and EAX,
    these modes are not tested against public test vectors (the usual C libraries
    do either not implement Serpent or OMAC/EAX).

  • The SEED cipher has been developed by KISA
    (Korea Information Security Agency). It uses 128-bit input/output data
    blocks and 128-bit keys. SEED is specified in ISO/IEC 18033-3 and
    in RFC 4269.

  • The 256-bit block cipher SHACAL-2
    is based on the compression function of SHA256. It supports keys sizes from 128 to 512 bits. SHACAL-2 is designed by Helena
    Handschuh and David Naccache and is the only recommended 256-bit block
    cipher of the NESSIE portfolio.

  • SkipJack
    is a compact 64-bit block cipher with 80-bit keys. It was
    designed by the NSA as an unbalanced Feistel network with 32 rounds; in
    1998 it was declassified and published by NIST (the specification was
    clarified in 2002).

  • XTEA (eXtended TEA) is another compact 64-bit block cipher with
    128-bit keys described by David Wheeler and Roger Needham.

    Archive: xtea_2013-01-07.zip
  • poly_32x32 uses 32 x 32 -> 64 bit multiplication
    and is default for compilers with u/int64 data types (D4+, FPC),
  • poly_16x16 with 16 x 16 -> 32 bit multiplication for all
    other compilers without int64.
  • During development I also
    translated poly_8x8: it is available as a separate file,
    but not actually used (slower for all tested CPUs/compilers).
