Securing 5G/6G Communications in Smart Cities: Novel SNOW-V/ZUC-256 Multimode Architectures
Evangelia Konstantopoulou, George S. Athanasiou, Nicolas Sklavos · 2023
In this article, area- and performance-efficient multimode architectures of SNOW-V and ZUC-256 stream ciphers for smart-city deployments are introduced. Efficient resource sharing of critical parts of the two algorithms together with sophisticated application of design optimization techniques, such as loop unrolling, led to low area solutions while the overall performance was kept high. The proposed designs were implemented in both FPGA (AMD Xilinx) and ASIC (22nm) technologies. The results are compared with standalone implementations of individual ciphers, state-of-the-art existing hardware implementations of individual ciphers, and existing SNOW 3G/ZUC-128 multimode topologies as well. It is the first time that multimode designs are proposed that include both SNOW-V and ZUC-256 algorithms.
