Abstract IPSec encrypts and authenticates the packets of IP protocol. Both sides of IP network layer communication use encryption authentication, data source authentication and integrity verification to ensure the integrity, confidentiality and anti replay of IP protocol packet transmission. In enterprise network management, we can usually use IPSec VPN technology to establish a secure channel to realize the secure communication between headquarters and branches.[1]
