Performance Analysis of IPSEC over Internet Protocol version 6 Networks

IPv6 is the next generation in internet protocol. It is developed by the Internet Engineering Task Force (IETF) to provide better performance and also to provide new services in comparison to IPv4. It is intended to serve for sufficient IP address space to meet the present Internet growth. Security attacks have been common across the Internet, therefore in order to protect IPv6 networks from security attacks; IPSec has made an inbuilt component of IPv6 to ensure the integrity, authenticity and confidentiality of data transmitted across the networks. IPSec is a networking layer protocol which is used to protect the data between two devices. IPSec encrypts and authenticates the packets before sending them across the Internet. This thesis mainly focus on the effects of different attacks like spoofing and DoS attack under IPv6 networks after using IPSec as a security to test the performance of the network. Implementation of IPSec can protect the network from security threats related to confidentiality and integrity of data. However, it appears powerless against availability threats of network.
