How this entity was disambiguated
This entity first appeared as the object of triple T18281255 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Parallelizable Message Authentication Code Context triple: [PMAC, fullName, Parallelizable Message Authentication Code]
-
A.
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.
-
B.
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.
-
C.
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.
-
D.
Davies–Meyer compression function
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.
-
E.
Message-Digest Algorithm 5
Message-Digest Algorithm 5 (MD5) is a widely known but now cryptographically broken hash function that produces a 128-bit hash value and was once commonly used for checksums and data integrity verification.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
