Resumo: |
Nowadays, cryptography is being widely used as a standard for securing data exchange on the Internet. For instance, in software-defined networking, it is possible to apply cryptography in the control plane channel. However, it may increase resource usage, and consequently it could compromise the switch performance mainly in low-cost switches. This work brings the possibility of balancing security and performance in the controller-switch communication. To achieve that, we manage the communication by considering the security flaws known from southbound API messages in order to perform an attack. On the one hand, messages that are considered sensitive are more securely managed but, on the other hand, messages that are considered harmless are handled with a focus on performance. Our results show that it is possible to successfully balance security and performance. |
