Project SHA3 (configuration)_eac3

Configuration settings for SHA-3 project in EACirc:

• SHA3

  • USAGE_TYPE
    determines how to use SHA-3 project
    201: distinguisher mode - tries to evaluate distinguisher between 2 streams of data

  • PLAINTEXT_TYPE
    210: counter mode - hash random counters incremented by 1

  • USE_FIXED_SEED
    0: begin counters from random value
    1: begin counters from the value set by SEED directive

  • SEED
    initial value for counters - taken only if USE_FIXED_SEED=1

  • ALGORITHM_1
    algorithm to use (see table of hash functions)
    99: random input

  • ALGORITHM_2
    2nd algorithm to use (if 2 are needed; table of hash functions)
    99: random input

  • HASHLENGTH_ALG_1
    length of the output hash in bits for algorithm1 (for supported length see table of hash functions)

  • HASHLENGTH_ALG_2
    length of the output hash in bits for algorithm2 (for supported length see table of hash functions)

  • BALANCED_TEST_VECTORS
    1: test vectors are balanced (50% algorithm_1, 50% algorithm_2)
    0: test vectors may not be balanced (ratio of test vector sources determined randomly, changes every test set)

  • LIMIT_NUM_OF_ROUNDS
    1: algorithms will run only a limited number of rounds
    0: algorithms will run unrestrained, i.e. as originally designed

  • ROUNDS_ALG_1
    number of rounds for the 1. algorithm (if limited)

  • ROUNDS_ALG_2
    number of rounds for the 2. algorithm (if limited)

  • GENERATE_STREAM
    0: normal mode
    1: data stream generation mode - generate stream of hashes 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.
