As we all know, network data transmission between different hosts is mainly completed through the TCP/IP network protocol. This is true for enterprise LAN data transmission and Internet data transmission. However, it is hard to figure out that no security was provided during the design of the TCP/IP protocol. That is to say, the TCP/IP protocol alone cannot guara
