SDN-based security mechanism

Nowadays most hardware configurations are being replaced with software configurations in order to virtualize everything is possible. At this rate, in the networking research domain, the concept of Software Defined Network (SDN) is evolving. This paper proposes an SDN-based security mechanism that provides confidentiality and integrity by using custom cryptographic algorithms between two routers. The mechanism is able to secure for both TCP and UDP traffic. It provides the possibility to choose what information to secure: the Layer 4 header and Layer 7 payload, or just the Layer 7 payload. The implementation of the proposed security mechanism relies on the Cisco model for SDN and is using OnePK API.
