With Ascon being selected as the new NIST lightweight cryptography standard, it is imperative to study how it lends itself to different use-cases that may not be covered directly by the original proposal. In this abstract, we focus on Message Authentication Codes (MACs). We study six ways of instantiating MACs using the Ascon permutations (Ascon-p). We compare these methods over multiple metrics, including throughput, hardware utilization, security margins/claims, side-channel friendliness and energy consumption of short and long messages. The comparison is performed with Xilinx Artix-7 FPGA as a target.
