How this entity was disambiguated
This entity first appeared as the object of triple T1500513 — 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.

-
A.
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.
-
B.
SDES
SDES (Session Description Protocol Security Descriptions) is a key management mechanism used to negotiate and convey cryptographic parameters for securing media streams in real-time communication protocols.
-
C.
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).
-
D.
RC5
RC5 is a symmetric-key block cipher designed by cryptographer Ronald L. Rivest, known for its simplicity, parameter flexibility, and use in various encryption applications.
-
E.
3DES
3DES (Triple DES) is a symmetric-key block cipher that applies the Data Encryption Standard (DES) algorithm three times to each data block to provide stronger encryption security.
- 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: Data Encryption Standard Description of subject: Data Encryption Standard is an older symmetric-key block cipher algorithm once widely used for data protection but now considered insecure and largely superseded by stronger standards.
