The ESP protocol provides encryption and integrity for the data Protection, the AH protocol only provides integrity protection for data. Generally speaking, IPSec VPN uses the ESP protocol and the AH protocol only Use in some cases where encryption is forbidden. 13.VPN can realize the following functions: data confidentiality protection, data integrity protection, data source id
