Target entity: Davies–Meyer Context triple: [SHA-2, compressionFunctionType, Davies–Meyer]
-
A.
Davies–Meyer compression function
chosen
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.
-
B.
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.
-
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.
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.
-
E.
Rijndael
Rijndael is a symmetric block cipher designed by Joan Daemen and Vincent Rijmen that was selected by NIST as the basis for the Advanced Encryption Standard (AES).
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
