Abstract

In a computer network, security in sending and receiving data is very important to ensure that the data sent does not fall to third parties, especially if the data is confidential. For this reason, implementation of methods for securing data on the network is needed. One solution to solving security problems in a public network is to use Protocol Authentication Header (AH) and Encapsulating Security Payload (ESP) tunneling. Protocol AH and ESP Include Protocol in the Internet Protocol Security (IPSec). IP Security is a protocol used to secure the transmission of datagrams in a TCP / IP-based internetwork, IPSec Encrypts data in the same layer as the IP Protocol and uses tunneling techniques to transmit information over the internet or in intranet networks safely. IPSec supports two security communication sessions, namely the Authentication Header (AH) Protocol which serves to offer user authentication and protection from several attacks, the analysis shows that sniffing attacks cannot intercept because the data is encrypted in the view using Wireshark.
