Phrase: Diffie–Hellman key exchange | Statement: [IKEv1, uses, Diffie–Hellman key exchange]

Target entity: Diffie–Hellman key exchange
Context triple: [IKEv1, uses, Diffie–Hellman key exchange]

• A. Diffie–Hellman key exchange chosen
  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. Dragonfly key exchange
  Dragonfly key exchange is a password-authenticated key exchange (PAKE) protocol designed to provide secure mutual authentication and key establishment resistant to offline dictionary attacks.
• D. Merkle puzzles
  Merkle puzzles are an early cryptographic protocol that introduced the concept of public-key exchange by allowing two parties to establish a shared secret over an insecure channel using computationally asymmetric “puzzle” problems.
• E. Massey–Omura cryptosystem
  The Massey–Omura cryptosystem is a public-key encryption scheme based on exponentiation in finite fields that enables secure communication without prior key exchange.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
