I am unable to understand how to do this with WolfSSL ​:neocat_pensive:​
create the advertisement keypair via EC point multiplication using the anti-tracking keys and the master beacon key d0
di = (d0 ∗ ui) + vi

I'd like to test the C code I wrote for this before flashing it to the tag, and compare the outputs to OpenHaystack's Swift code, we'll see if that's possible

@kitten Antonia just told me that she would like to reply to you but she has too much mathematical background to give you a concise reply that would answer your question or help you understand anything.

Meanwhile I have no idea whatsoever what any of you are doing here, but that's totally irrelevant because despite that, all of this is happening because I said so blobcatlove :3

@kitten what are d0 and ui? are both of them points or is one of them a scalar? maybe it means scalar multiplication

@kitten
A widespread name for this operation is also elliptic curve point multiplication, but this can convey the wrong impression of being a multiplication between two points.
yeah they mean scaling then. i hate when mathmaticians do not use the proper words :(

@kitten this might be something that @soatok can offer some pointers on

@mei ui and vi are the split output of 72 bytes of the ANSI X.963 key derivation function, and d0 is supposed to be a private key
