May 24, 2019 Difference Between IKEv1 and IKEv2 | Difference Between “IKE,” which stands for “Internet Key Exchange,” is a protocol that belongs to the IPsec protocols suite. Its responsibility is in setting up security associations that allow two parties to send data securely. IKE was introduced in 1998 and was later superseded by version 2 roughly 7 years later. How can I setup Site to Site VPN with IKE2 Dynamic client IKE (Phase 1) Proposal; Exchange: IKEv2 Mode; DH Group: Group 5; Encryption: AES-256; Authentication: SHA-512; Life Time (seconds): 28800 . NOTE:The menu "DH Group", "Encryption" and "Authentication" will be gray-out since "IPSec Primary Gateway Name or Address" in General tab … Reference: IKE Encryption and Authentication Algorithms
You can use SHA-1, SHA-2, or MD5 as the algorithm the VPN gateways use to authenticate IKE messages from each other. SHA-2 is the only secure option. Encryption — Encryption keeps the data confidential. You can select DES, 3DES, or AES, or AES-GCM. AES and AES-GCM variants are the only secure options.
IKEv1 Protocol, IKEv1 message exchange, IKEv1 Main
IKE itself is just key exchange protocol, providing secure session keys negotiation. It works together with encryption and authentication modules. So, IKE itself just provides session with secure keys. Moreover, it was developed on far 2005. It is oftenly being used together with ESP and AH protocols.
