Implementations of the PRESENT algorithm for a Rasberry Pi PICO
Two implementations of the PRESENT algorithm located in the src/ directory - one reference implementation (present_ref/crypto.*) and another utilising (32-fold) bitslicing (present_bs/crypto.*).
Testing script, for both, is available against specific test vectors.
Note: this was developed as a team as part of University coursework. This is designed to pass a series of provided tests, not to be used in production. Code was inspired & adapted in part from lecture contents and other sources. I am hosting this here for fun (aka as a cheap backup and to showcase work)
Run build.sh
Flash the appropriate .uf2 from the build/ directory onto your PICO and use the appropriate test_against_testvectors.py scripts, supplying the serial port to the PICO.
