Cobra-de1 / SCRA

C++ SCRA implementation

C++ SCRA implementation

Decription

Structure-free and Compact Real-time Authentication (SCRA) implementation using standand C++ library and sha3-256 library for hash function

Detail

Security: 128 bit

Digital signature base: C-RSA 3072 bit

Hash function: sha3-256

L = 32, b = 8

How to run

This code is running in linux, if you use windows, recompile the SCRA.o and sha3.o by following:

• Go to folder sha3 type gcc -c sha3.c -o sha3.o

• Copy new sha3.o and sha3.h into SCRA folder

• Go to folder SCRA and type gcc -c SCRA.c -o SCRA.o -l sha3.o

• Copy new SCRA.o and sha3.o in to lib folder

1) Build with VisualStudio Code

2) Compile

gcc -g2 -O3 -DNDEBUG verify.c -o verify -L/lib -l:sha3.o -l:SCRA.o -I/include -Wall -lgmp

gcc -g2 -O3 -DNDEBUG verify.c -o verify -L/lib -l:sha3.o -l:SCRA.o -I/include -Wall -lgmp

gcc -g2 -O3 -DNDEBUG verify.c -o verify -L/lib -l:sha3.o -l:SCRA.o -I/include -Wall -lgmp
