Our hardware design is especially tailored for the quadratic extension field F-22n ; with n = 127; which allows us to attain a security level close to 128 bits. We explore extensively the usage of digit-based and Karatsuba multipliers for performing the quadratic field arithmetic associated to GLS elliptic curves and report the area and time performance obtained by these two types of multipliers. Targeting a XILINX KINTEX-7 FPGA device, we report a hardware implementation of our design that achieves a delay of just 3.98 mu s for computing one scalar multiplication. This allows us to claim the current speed record for this operation at or around the 128-bit security level for any hardware or software realization reported in the literature.eninfo:eu-repo/semantics/closedAccessConference ObjectN/AWOS:000400775800021
