How this entity was disambiguated
This entity first appeared as the object of triple T1096790 — 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.

C.
ZRTP
ZRTP is a cryptographic key-agreement protocol designed to enable end-to-end encryption for real-time voice and video communications over RTP-based systems.
-
D.
TLS
TLS (Transport Layer Security) is a cryptographic protocol that secures data transmitted over networks by providing encryption, authentication, and integrity between communicating applications.
-
E.
QUIC
QUIC is a modern, multiplexed transport protocol developed by Google and standardized by the IETF that runs over UDP to provide faster, more secure, and reliable web connections than traditional TCP-based HTTPS.

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: DTLS-SRTP Description of subject: DTLS-SRTP is a security protocol framework that uses Datagram Transport Layer Security to negotiate keys and provide encryption and authentication for Secure Real-time Transport Protocol media streams, commonly used in VoIP and WebRTC.
