Small lightweight hash functions in FPGA
Carlos Andres Lara-Nino, Miguel Morales‐Sandoval, Arturo Díaz-Pérez · 2018
This paper presents hardware realizations of two lightweight hash function families on FPGA: spongent and LHash. The assessment provided for both cryptographic primitives is in terms of area, performance, and energy consumption, when implemented in LUT-4 and LUT-6 FPGA technology for equivalent security levels. To the best of our knowledge, this paper reports the most compact spongent FPGA implementation and the first FPGA implementation of LHash.
