How this entity was disambiguated

This entity first appeared as the object of triple T9932099 — 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.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Signal protocol
Context triple: [Ed25519, usedIn, Signal protocol]

A. Noise protocol framework
The Noise protocol framework is a modular cryptographic handshake framework for building secure communication protocols using combinations of well-studied primitives.
B. Diffie–Hellman key exchange
Diffie–Hellman key exchange is a foundational cryptographic protocol that enables two parties to securely establish a shared secret over an insecure communication channel.
C. The Sigma Protocol
The Sigma Protocol is a posthumously published thriller novel by Robert Ludlum that follows a man uncovering a vast global conspiracy tied to secret financial and political powers.
D. Secure Information Exchange Network Application
The Secure Information Exchange Network Application (SIENA) is Europol’s secure communication platform used by law enforcement authorities across Europe to exchange sensitive criminal intelligence and operational information.
E. Temporal Key Integrity Protocol
Temporal Key Integrity Protocol (TKIP) is a legacy wireless security algorithm designed to enhance WEP encryption in early Wi‑Fi networks by dynamically changing encryption keys.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
