C.
Substitution–permutation network
A substitution–permutation network is a symmetric-key cryptographic design that secures data by repeatedly applying nonlinear substitutions and bitwise permutations to achieve confusion and diffusion.
-
D.
Point-to-Point Encryption Standard
The Point-to-Point Encryption Standard is a PCI SSC security framework that defines requirements for encrypting payment card data from the point of capture to the secure decryption endpoint to reduce fraud and PCI DSS scope.
-
E.
Advanced Encryption Standard
Advanced Encryption Standard is a widely used symmetric block cipher standard that secures digital data in applications ranging from wireless networks to government communications.
- F. None of above. chosen

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
