How this entity was disambiguated

This entity first appeared as the object of triple T21191350 — 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: Internet Key Exchange Protocol Version 2
Context triple: [RFC 4555, updatesProtocol, Internet Key Exchange Protocol Version 2]

A. 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.
B. SIGMA key exchange protocol
The SIGMA key exchange protocol is a cryptographic protocol designed to provide secure authenticated key exchange with strong security guarantees and has been widely used as the basis for protocols like IKE in IPsec.
C. Negotiated Finite Field Diffie-Hellman Ephemeral Parameters for Transport Layer Security (TLS)
"Negotiated Finite Field Diffie-Hellman Ephemeral Parameters for Transport Layer Security (TLS)" is an IETF standard (RFC 7919) that defines secure, standardized finite-field Diffie-Hellman parameter sets for use in TLS to improve cryptographic security and interoperability.
D. Public-Key Cryptography Standards
Public-Key Cryptography Standards (PKCS) is a collection of widely used specifications developed by RSA Laboratories that define formats and protocols for implementing public-key cryptography in software and systems.
E. Public-Key Cryptography Standards #7
Public-Key Cryptography Standards #7 (PKCS #7) is a widely used cryptographic standard that defines a general syntax for digitally signing and encrypting data, forming the basis for formats like S/MIME.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
