They are authored by Manuel Pégourié-Gonnard. p256-m is a minimalistic implementation of ECDH and ECDSA on NIST P-256, especially suited to constrained 32-bit environments. Mbed TLS documentation for integrating drivers uses p256-m as an example of a software accelerator, and describes how it can be integrated alongside Mbed TLS. It should be noted that p256-m files in the Mbed TLS repo will not be updated regularly, so they may not have fixes and improvements present in the upstream project. |
