SDN-based access authentication and automatic configuration for IPSec

As a standard network and a network architecture with an open standard, IPSec guarantees the security of communication data by encryption. IPSec VPN's various configuration parameters and commands pose difficulty in manual faults removing, and the large number of client applications makes its efficiency even lower. The paper proposes a method based on SDN network archetecture for IPSec automatic configuration management to solve the problem. This method is combined with SDN controllers and OpenFlow switches to improve its management configuration and user access management efficiency.
