In the previous article, the experimental environment was built. The protocol analysis can be performed once the IKE/IPSEC protocol is fully run and the relevant output and capture packets are collected. During the analysis, we will use the output of the IKE process and the Wireshark grab packet, combined with the relevant RFC, using Python to verify the calculation. First look at the full operation of the Protocol (filtering out irrelevant messages,
