IKEv2 works by using an IPSec-based tunneling protocol to establish a secure connection. One of the single most important benefits of IKEv2 is its ability to reconnect very quickly in the event that your VPN connection gets disrupted. With quick reconnections and strong encryption IKEv2 makes an excellent candidate to use on Windows or iOS.

IKEv2 negotiates the secure communication channel and IPSec encrypts and de-encrypts the traffic received from an insecure backhaul to provide data confidentiality, data integrity, and authentication. IPSec also provides support for the anti-replay protocol that provides IP packet-level security to prevent interception and modification of message packets that are being sent between a source

In computing, Internet Key Exchange (IKE, sometimes IKEv1 or IKEv2, depending on version) is the protocol used to set up a security association (SA) in the IPsec protocol suite. IKE builds upon the Oakley protocol and ISAKMP. IKE uses X.509 certificates for authentication ‒ either pre-shared or distributed using DNS (preferably with DNSSEC) ‒ and a Diffie–Hellman key exchange to set up a 02/10/2016 27/01/2014 IKEv2 stands for Internet key exchange version two, and IPSec refers to the Internet protocol security suite. Together, they form a VPN protocol. A VPN protocol, or a “tunneling protocol,” is the set of instructions your device uses to negotiate the secure encrypted connection that forms the network between your […]

The IPsec protocols use a security association, where the communicating parties establish shared security attributes such as algorithms and keys. As such IPsec provides a range of options once it has been determined whether AH or ESP is used. Before exchanging data the two hosts agree on which algorithm is used to encrypt the IP packet, for example DES or IDEA, and which hash function is used
