Micro-ECC for RIOT.
This port of Micro-ECC to RIOT is based on the Micro-ECC upstream and adds
hwrng_read (provided by RIOT) as the default RNG function if it is available on the target platform. This port also fixes a minor issue with unused variables in the upstream code.
to your Makefile.
Before using the Micro-ECC library, you need to check the
Makefile.features of your target board to see if
periph_hwrng is provided.
If it is provided, you may safely use
uECC_make_key to generate ECDSA key pairs and call
uECC_verify to sign/verify the ECDSA signatures.
If not, you cannot use
uECC_sign APIs anymore. The ECDSA keys have to be generated on a platform with HWRNG support (e.g.,
native) and transferred to your target device. You need to use
uECC_sign_deterministic to perform ECDSA deterministic signing (standardized by RFC 6979). You can still use
uECC_verify to verify the signatures from both signing APIs.
uECC_sign APIs on platforms without HWRNG support will lead to compile failure.
Examples of using these uECC APIs can be found in the
test folder of the Micro-ECC upstream.
