An Efficient LBlock Lightweight Block Cipher Coprocessor on RISC-V: Combinational Key Schedule Fusion and S-Box-to-LUT Mapping

2026 · Symmetry

Resource-constrained Internet-of-Things (IoT) terminals require encryption engines that combine low silicon cost with adequate throughput, a balance that is hard to reach with general-purpose software alone. This paper presents an LBlock lightweight block cipher coprocessor …
