SDN Security Channel Constructed Using SM9

In relation to the utilization of SDN within the production environment, the process of constructing a secure flow table transmitting channel has elicited concerns from operations and maintenance personnel and researchers. Despite the fact that research findings can satisfy the security communication requirements of controllers and switches, they typically require escalated investment or operation and maintenance expenses, thereby making its implementation challenging. Aiming to rectify this, we have devised a streamlined secure channel construction methodology, employing the SDN device ID and timestamp as identity tags, and designing an identity authentication and password negotiation approach founded on these identity tags. Conclusively, the security evaluation of this methodology verifies that our method presents robust security in EUF-CMA.
