Abstract
Software-defined networking (SDN) is a pioneering paradigm that adds a new level of management and programmability to computer networks. Despite its benefits, SDN opens the door for new attacks against the network by targeting different SDN components, especially when they need to interact with each other through application programming interfaces (APIs). In this work, we focus on protecting those APIs by proposing SDN-API-Sec-Fast, a cross-domain access control method based on the key characteristics of blockchain technology. We enhance our previous work SDN-API-Sec by introducing SDN-API-Sec-Fast, which combines conflict detection with read-only mode to achieve better performance. We investigate the performance of the blockchain side and the overall authorization process.
期刊介绍：
Annals of Telecommunications is an international journal publishing original peer-reviewed papers in the field of telecommunications. It covers all the essential branches of modern telecommunications, ranging from digital communications to communication networks and the internet, to software, protocols and services, uses and economics. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies in computers, communications, content management towards the emergence of the information and knowledge society. As a consequence, the Journal provides a medium for exchanging research results and technological achievements accomplished by the European and international scientific community from academia and industry.
