Abstract
Value-added 5G verticals are foreseen to be delivered as a service chain over multiple network operators with extensive outsourcing of Virtual Network Functions (VNFs). In this short paper we introduce the initial design of SafeLib, a software middlebox platform based on Intel SGX, which protects user traffic, VNF code, policy input and state in such scenarios, while also retaining high performance. Augmenting the smart integration of existing hardware and software building blocks with new secure elements, the SafeLib architecture shows considerable promise in a carrier-grade service context.
