Literature Review on Using Internet Protocol Security (IPsec) on network Connectivity

Internet Protocol Security (IPsec) is a widely used implementation process for Virtual Private Networks (VPNs). IPsec, introduced by the Internet Engineering Task Force (IETF), is a common tunneling technology for Virtual Private Networks that enhances the security features of the network layer, allowing several segments of a private network to function as a single segment. This research analyzes the overheads associated with IPsec. The results of this review paper demonstrate that IPsec remains within appropriate operating ranges even when additional packets are inserted. IPsec consists of two protocols, AH and ESP, which safeguard IP packets. As a result of the analysis, a novel IPsec service has been implemented. This new scheme reduces the workload for on-the-spot devices and ensures compatibility with existing structured solutions. Additionally, the reduced overhead of the packet leads to fewer cryptographic calculations.
