IPSec
IPSec (Internet Protocol Security) is a protocol suite for securing
Internet Protocol (IP) communications by authenticating and
encrypting each IP packet of a communication session. IPSec
also includes protocols for establishing mutual authentication
between agents at the beginning of the session and negotiation
of cryptographic keys to be used during the session.
IPSec is an end-to-end security scheme operating in the
Internet Layer of the Internet Protocol Suite. It can be used in
protecting data flows between a pair of hosts (host-to-host),
between a pair of security gateways (network-to-network), or
between a security gateway and a host (network-to-host).
