ABSTRACT
The rapid development in the multi-radio access technology (M-RAT) has created new challenges for the next-generation cellular operators and service providers. To handle these multi-radio access technologies, cellular platforms need to be scalable and flexible. Cloud radio access network (C-RAN) is a centralized base station architecture that uses cloud computing and virtualization technology to provide RAN services. The scalable platform of C-RAN not only allows M-RAT technology but also increases service complexity and RAN insecurities. In this chapter, we propose a privacy preservation and authentication mechanism to secure the baseband unit (BBU) pool from different attacks like denial of service, man in the middle, and jamming attacks. The proposed protocol is validated using protocol validation tools like AVISPA and SCYTHER. The result shows that the protocol is partially able to secure the BBU-pools from the possible baseband attacks.
