How this entity was disambiguated
This entity first appeared as the object of triple T1798500 — 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: BEAST attack Context triple: [TLS 1.0, hasVulnerability, BEAST attack]
-
A.
Spritz cipher
Spritz cipher is a modern stream cipher and hash function designed by Ronald Rivest and Jacob Schuldt as a more secure and flexible successor to RC4.
-
B.
Shamir’s attack on RSA with low decryption exponent
Shamir’s attack on RSA with low decryption exponent is a cryptanalytic method that exploits unusually small private exponents in RSA to efficiently recover the secret key and break the encryption.
-
C.
differential cryptanalysis
Differential cryptanalysis is a powerful method of cryptanalysis that studies how differences in input can affect the resultant differences at the output of a cipher to reveal information about its secret key.
-
D.
Merkle puzzles
Merkle puzzles are an early cryptographic protocol that introduced the concept of public-key exchange by allowing two parties to establish a shared secret over an insecure channel using computationally asymmetric “puzzle” problems.
-
E.
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.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: BEAST attack Description of subject: The BEAST attack is a cryptographic exploit that targets vulnerabilities in early versions of TLS/SSL to decrypt secure HTTPS traffic by abusing weaknesses in block cipher modes like CBC.
