Welcome to the resource topic for 2022/254

Unprotected and Masked Hardware Implementations of Spook v2

Authors: Charles Momin, Gaëtan Cassiers, François-Xavier Standaert


We describe FPGA implementations of the Spook candidate to the NIST lightweight cryptography competition in two flavors. First, unprotected implementations that exhibit the excellent throughput and energy consumption for the area target specified by the NIST benchmarking initiative. Second, protected implementations leveraging the leveled implementation concept that the Spook design enables and confirming the significant performance gains that it enables.
