Ipsec introduction

WebIPsec SAs define which network traffic is to be secured and how it has to be encrypted and authenticated. A CHILD_SA consists of two components: The actual IPsec SAs (two of them are established, one in each direction) describing the algorithms and keys used to encrypt and authenticate the traffic. 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).
