  • A. Merkle–Damgård construction
    The Merkle–Damgård construction is a fundamental method for building collision-resistant cryptographic hash functions from fixed-size compression functions, used in many classic hash algorithms like MD5 and SHA-1.
  • B. Whirlpool hash function
    Whirlpool is a cryptographic hash function designed by Vincent Rijmen and Paulo S. L. M. Barreto, known for its wide-pipe construction and strong security properties suitable for digital signatures and data integrity.
  • C. Keccak
    Keccak is a cryptographic hash function family that forms the basis of the SHA-3 standard, known for its sponge construction and strong security properties.
  • D. Hash-based Message Authentication Code
    Hash-based Message Authentication Code (HMAC) is a cryptographic mechanism that uses a hash function and a secret key to verify both the integrity and authenticity of a message.
  • E. Carter–Wegman MACs
    Carter–Wegman MACs are a family of message authentication codes that use universal hashing combined with a secret key to provide efficient and provably secure authentication.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
