Davies–Meyer compression function

Target entity: Davies–Meyer compression function
Context triple: [RIPEMD-160, uses, Davies–Meyer compression function]

• 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.

Target entity: Davies–Meyer compression function
Target entity description: The Davies–Meyer compression function is a classic construction in cryptography that builds a hash function’s compression step from a block cipher by feeding the cipher’s output back into the input via XOR.
