TRUFL: Distributed Trust Management framework in SDN
This addresses trust management inefficiencies in SDN for cloud infrastructure, though it appears incremental as it builds on existing distributed approaches.
The paper tackles the lack of scalable trust setup and verification in Software Defined Networking (SDN) by proposing TRUFL, a distributed trust management framework that achieves faster transfer rates and reduced latency compared to centralized methods, and scales well with the number of OpenFlow rules.
Software Defined Networking (SDN) has emerged as a revolutionary paradigm to manage cloud infrastructure. SDN lacks scalable trust setup and verification mechanism between Data Plane-Control Plane elements, Control Plane elements, and Control Plane-Application Plane. Trust management schemes like Public Key Infrastructure (PKI) used currently in SDN are slow for trust establishment in a larger cloud environment. We propose a distributed trust mechanism - TRUFL to establish and verify trust in SDN. The distributed framework utilizes parallelism in trust management, in effect faster transfer rates and reduced latency compared to centralized trust management. The TRUFL framework scales well with the number of OpenFlow rules when compared to existing research works.
