IKEv2 is a tunneling protocol that provides online security and privacy by using encryption, authentication, and key exchange methods to create a secure connection. It is an open standard, which means that any software developer can implement this protocol.
It is an acronym for Internet Key Exchange v2. It is a protocol that allows you to connect to the internet via a virtual private network which encrypts your internet traffic and allows you to connect to remote networks. IKEv2 VPN is a protocol that can be used to create a secure connection from one computer to another computer or device. IKEv2 is not just about encryption, but it also includes authentication and key exchange. This protocol was developed by Cisco and Microsoft to improve the security and privacy of VPNs. For it is an open standard so anyone can develop for it. There are several issues that IKEv2 has over IKEv1, and the main one is speed. IKEv2 is faster and more efficient than OpenVPN. However, OpenVPN is a more secure protocol and has been around for a while.
What are the differences between IPSec Xauth PSK and IPSec Xauth RSA? Which is more secure, ikev2 or other protocols?
IPSec Xauth PSK is in fact superior to IPSec Xauth RSA because its design makes it more straightforward.but less secure than IPSec RSA. However, ikev2 in the compare with other protocols are more secure than IPSec Xauth RSA.
Security Comparison: IKEV2 > IPSec Xauth RSA > IPSec Xauth PSK
