IKEv1

Target entity: IKEv1
Context triple: [IKEv2, obsoletes, IKEv1]

• A. IKEv2
  IKEv2 is a modern key management and security association protocol used to establish and maintain secure VPN connections in IPsec-based networks.
• B. IPsec
  IPsec is a suite of protocols that provides secure, encrypted communication over IP networks by authenticating and protecting the integrity and confidentiality of data packets.
• C. IEEE 802.11i
  IEEE 802.11i is a Wi‑Fi security standard that enhances wireless network protection by defining robust encryption and authentication mechanisms, including WPA2.
• D. IKE Phase 2
  IKE Phase 2 is the stage of the IPsec key exchange process where security associations are negotiated and keys are established for protecting actual data traffic between peers.
• E. Encapsulating Security Payload
  Encapsulating Security Payload (ESP) is a core IPsec protocol that provides confidentiality, integrity, and optional authentication for IP packets through encryption and encapsulation.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
