Securing Virtual Network Function (VNF) in Telco Cloud
In the fifth generation mobile communication architecture (5G), network functions which traditionally existed as discrete hardware entities based on custom architectures, are replaced with dynamic, scalable Virtual Network Functions (VNF) that run on general purpose (x86) cloud computing platforms, under the paradigm Network Function Virtualization (NFV). The shift towards a virtualized infrastructure poses its own set of security challenges that need to be addressed. One such challenge that we seek to address in this paper is providing integrity, authenticity and confidentiality protection for VNFs.
