How does IKEv2 authentication work?

IKEv1 supports authentication via pre-shared keys, digital signatures, and public key encryption. IKEv2 supports pre-shared keys, digital signatures and EAP. However, IKEv2 supports asymmetric authentication: One side can authenticate using pre-shared keys while the other side uses digital signatures.

What is the difference between OpenVPN and IKEv2?

Performance: In many cases IKEv2 is faster than OpenVPN since it is less CPU-intensive. There are, however, numerous variables that affect speed, so this may not apply in all use cases. From a performance standpoint with mobile users, IKEv2 may be the best option because it does well establishing a reconnection.

What layer is IKEv2?

first proposal is a layer 3 IPsec tunnel mode VPN architecture. It uses IKEv2 protocol to exchange SAs which need to build IPsec tunnels.

Does IKEv2 use TCP?

The IKEv1 protocol does not support TCP support. TCP support is only available when IKEv2 is used. This protocol is based on UDP and uses UDP port 500 and 4500. Once the IKE negotiation has completed, IP packets are encrypted and transported using the ESP protocol (protocol 50).
