Abstract

Network slicing is a powerful tool that provides 5G and future networks a robust means for managing cross-application QoS, dynamic traffic migration in response to network events, and in-network data aggregation and computation. Unfortunately, slicing inherits many of the security challenges of cloud and edge computing such as side-channel information leakage, while also encountering new challenges posed by multi-domain authorization and quantum computing. Many extant mechanisms, such as PKI, are insufficient in the face of quantum computers, and existing side-channel mitigations impose heavy overhead costs while only providing defense against known attacks. In this paper, we describe a novel approach to protecting slice control information through the use of Homomorphic Encryption (HE). HE allows quantum-resilient validation and distribution of critical information, while also enabling hierarchical …
