Cryptography on LPC8N04

grasshopper — Sat, 31 Jul 2021 12:50:07 GMT

I'm looking for a cryptography library for my LPC8N04 Development Board. I tried to cross-compile libsodium, but for some reason I get "undefined reference" linker errors when compiling code which includes library functions. I have little experience with embedded C programming, so I'm a little lost. Does anyone here have experience with crypto libraries for the Arm Cortex M0 and could help me getting one to work on my chip? Specifically, I'm looking for an implementation of DSA/ECDSA and a SHA hash function.

The only solution we have is TN00040 which gives an overview of how build an application to support encrypted over the air firmware update using NFC through a Secondary Boot Loader (SBL).

Hope this will help you.

Have a nice day,
