Project CAESAR (configuration)

Configuration settings for CAESAR project in EACirc:

• CAESAR
  • USAGE_TYPE
    determines how to use CAESAR project
    301: distinguisher mode - tries to evaluate distinguisher between 2 streams of data
  • ALGORITHM
    algorithm to use (see table of CAESAR candidates)
  • LIMIT_NUM_OF_ROUNDS
    1: algorithms will run only a limited number of rounds
    0: algorithms will run unrestrained, i.e. as originally designed
  • ALGORITHM_ROUNDS
    number of rounds for the chosen algorithm (if limited)
  • PLAINTEXT_LENGTH
    number of bytes used as plaintext
  • AD_LENGTH
    number of bytes used as associated data
  • PLAINTEXT_TYPE
    structure of the plaintext used
    0: zeroes - binary zeroes
    1: random once - random at cipher initialization, reused for other test vectors
    2: counter - zero-initialized counter incremented by 1
    3: random - random stream
  • KEY_TYPE
    structure of the key used -- same options as PLAINTEXT_TYPE
  • AD_TYPE
    structure of the associated data used -- same options as PLAINTEXT_TYPE
  • SMN_TYPE
    structure of the secret message number used -- same options as PLAINTEXT_TYPE
  • PMN_TYPE
    structure of the public message number used -- same options as PLAINTEXT_TYPE
  • GENERATE_STREAM
    0: normal mode
    1: data stream generation mode - generate stream of data according to settings (used for statistical testing, e.g. Dieharder) Data will be saved to file.
    Note: This mode breaks the consistency of generators and therefore prevents the evolution from starting after finishing stream generation.
  • STREAM_SIZE
    0: generate unlimited stream (is sent to cout instead of file)
    n: minimal size of generated stream (in bytes, saved to file)
    Note: This directive is considered only if GENERATE_STREAM=1.
