Authenticated mobile groups to secure the backhaul: A new paradigm and challenges

In this paper, it is proposed to use group communication cryptographic protocols as a new security paradigm. This new paradigm aims at redesigning the security of small cell communications over an insecure mobile backhaul. The Heterogeneous Networks are positioned and a review of the current security mechanisms and their flaws is provided. A security and performance comparison between the current mechanisms and our proposition is developed, and this comparison leads to new development opportunities to increase the security of the overall backhauling.
