A Systematic Mapping about Anonymization Services for Software-Defined Networking

Software-Defined Networking (SDN) allows the decouple of the network control from the dataflow, which facilitates the management and the view from network, like resources configuration and a dynamic change of the network. However, one of the biggest challenges of the SDN architecture is the security issue. The decouple of the control from the dataflow towards to new challenges to guarantee the security of the network on a desirable level, avoiding attacks like ´´Man in the Middle'' or ´´Denied of Service''. Many studies have been made to develop architectures and services more secure, using protocols, cryptographic algorithms and anonymization techniques. This paper maps the anonymization techniques developed for SDN and published on computing scientific databases. From all the 67 papers found, they were analyzed and selected to gathered the results of the systematic mapping. Based on that, the analysis shows that studies have been made in anonymization field, but a limited number of anonymization services are under development. So, our work presents as result a research field with a growth perspective on SDN, which can improve the security on this area.
