We have a need to verify an secp128r1 ECDSA signature. I see that this is not one of the curves supported by the CC310, but I'm looking into creating the CRYS_ECPKI_Domain_t myself. Most of the members can be easily found as defined by the ECC standard, but there are a few that seem specific to the CC310, such as llfBuff, modSizeInBits, ordSizeInBits, and barrTagSizeInWords.
Has anyone successfully used the CC310 on this curve type? Is it possible?
