WebWe would like to show you a description here but the site won’t allow us. In computing, Internet Protocol Security (IPsec) is a secure network protocol suite that authenticates and encrypts packets of data to provide secure encrypted communication between two computers over an Internet Protocol network. It is used in virtual private networks (VPNs). IPsec includes protocols for establishing mutual authentication between agents at the beginning of a session and negotiation of cryptographic keys to use during the session. IPsec can protect da…

Web2.2. Non-Expansion Policy If the total size of a compressed payload and the IPComp header, as defined in section 3, is not smaller than the size of the original payload, the IP datagram MUST be sent in the original non-compressed form. To clarify: If an IP datagram is sent non-compressed, no IPComp header is added to the datagram. WebThe IPSec layer sits between the transport and network layers in transport mode. In tunnel mode, data is transferred back and forth between the network and IPSec layers before being sent back to the network layer. The two modes are compared in the following figure.
