Simple and secure ECC and ECDSA

This is a project for the primitives in Elliptic Curve Cryptography (ECC). It is forked from https://github.com/esxgx/easy-ecc while some modifications have been done to make it easier to build and read, as well as to make it a little more efficient.

There are several branches for different versions, ECC-8, ECC-32 and ECC-64, aiming at platforms with different sizes of words. Algorithms in these branches are generally the same.

Use

you can use 8-bit, 32-bit or 64-bit version for your convenience.

git checkout ecc-{8 or 32 or 64}

compiling

mkdir build-release 
cd build-release
cmake ../
make

or

mkdir build-debug 
cd build-debug 
cmake -DCMAKE_BUILD_TYPE=Debug ../
make

for Arduino mega 2560, use

mkdir build-avr 
cd build-avr 
cmake --DCMAKE_BUILD_TYPE=Release-avr ../
make 
make keytest-upload 
make keytest-serial

run the test programs

./bin/keytest         -- key make, encrypt, decrypt, sign and verify 
./bin/pointtest       -- test scalar multipication or point addition
./bin/fieldtest       -- test number multiplication and squaring
