WebIPsec (Internet Protocol Security) is a suite of protocols that secure network communication across IP networks. It provides security services for IP network traffic such as encrypting sensitive data, authentication, protection against replay and data confidentiality. IPsec uses the following protocols to secure the IP network traffic: WebInternet Key Exchange. 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. [1] IKE uses X.509 certificates for authentication ‒ either pre-shared or distributed using ...
