Target entity: DNSSEC KSK Context triple: [DNSSEC ZSK, rotatedMoreFrequentlyThan, DNSSEC KSK]
-
A.
DNSSEC ZSK
DNSSEC ZSK (Zone Signing Key) is the cryptographic key used in DNS Security Extensions to sign individual DNS zone data, ensuring the authenticity and integrity of DNS responses.
-
B.
DNSSEC
DNSSEC (Domain Name System Security Extensions) is a suite of specifications that adds cryptographic authentication and integrity protection to DNS data to prevent attacks such as cache poisoning and spoofing.
-
C.
DNSSEC root key signing ceremony
The DNSSEC root key signing ceremony is a highly controlled, regularly scheduled cryptographic event where trusted personnel generate and manage the root cryptographic keys that secure the global Domain Name System.
-
D.
TSIG
TSIG (Transaction SIGnature) is a security protocol used in DNS to authenticate and protect DNS messages between servers using shared secret keys and message authentication codes.
-
E.
Domain Name System root zone
The Domain Name System root zone is the top-level, authoritative directory of the internet’s domain name hierarchy, mapping top-level domains to their corresponding name servers.
- 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: DNSSEC KSK Description of subject: The DNSSEC KSK (Key Signing Key) is a long-term cryptographic key used to sign and authenticate a zone’s DNSKEY records, forming the trust anchor at the top of the DNSSEC validation chain.
