dorsal1464 / ascon-p Goto Github PK

In this repository are various secure masking designs for the Ascon-p permutation block. most designs were implemented in assembly, the rest were implemented in C. all implementation were designed to work with a randomness cache buffer, to increase performance (or, to eliminate waiting time from pseudo random generator)

setup.sh - perform required installations on the machine. make (Makefile) - to build for x86 / x64 / armv7 / aarch64 processors, and run. running arm requires emulations...

inside scripts, there are: benchmark.py - benchmark cycles per bit, randomness usage, for both our generic masking and usuba. codesize.py - calculate the codesize for every implemntation. datapath.py - simulate the time required for each technology to copy a large buffer.

The implementations were designed by Dor Salomon as part of a research activity with the Secured Electronic Systems (Selecsys) LAB at Bar-Ilan University, under the supervision of Dr. Itamar Levi.
