Simulation study demonstrates reduced slice blocking and optimized resource usage in 5G networks, highlighting secure allocation against side-channel attacks.
Key Points
To design an efficient resource allocation strategy that maximizes the number of accommodated network slices in 5G radio access networks while protecting against hardware-level side-channel attacks.
Developed a side channel attack-aware resource allocation (SCA-RA) algorithm tailoring heterogeneous IT and transport resource distribution to individual slice security requirements.
Simulated algorithm performance under dynamic slice requests across two distinct 5G radio access network operational scenarios against benchmark allocation schemes.
The SCA-RA algorithm reduced the blocking probability of dynamic network slice requests compared to benchmark allocation methods.
IT and transport resource utilization were optimized across network infrastructure while enforcing logical isolation against hardware-sharing attacks.
