ABSTRACT
5G is a fifth-generation mobile network that provides efficient wireless communication over the previous generation. It provides faster data speeds, lower delays, and more capacity to connect with many devices simultaneously. In this work, network slicing in 5G networks is discussed with regard to security measures which include QKD(Quantum Key Distribution) and PQC(Post-Quantum Cryptographic). It allows for the formation of numerous granular and independent virtual networks based on a shared physical network. The model explores security where QKD keys address links and encompass PQC to counter other quantum technology threats in the future. Furthermore, there are reliability measures introduced, including route adjustments, with a self repairing capability for link failure in multi-slice networks. In this approach, the security and reliability features are incorporated in 5G network slicing to address the delivery of the services in the next-generation networks.
