Tool/software:
We are using the MSP420FR5994 in a device that performs certain measurements. Those measurements are stored locally and sent to our server in a batched format. We are exploring the possibility of origin verification through digital signing (i.e. locally stored private key + hash of batch of data). Does anyone have any experience of using the RSA algorithm in this microcontroller? Is there a library we can use? Is it prohibitively expensive in terms of memory or processing power? Before we go any further in this project, we’d love to hear from anyone who has attempted this before.
