09:49 < SopaXorzTaker> of scientific interest
09:50 < SopaXorzTaker> can I have an EMI recording of a CPU performing secp256k1 privtopub?
09:50 < SopaXorzTaker> Preferably single-core, such as Raspberry Pi 1
10:12 < sipa__> TD-Linux: ^
10:23 < TD-Linux> SopaXorzTaker, I don't have a recording on hand, but could make one.
10:24 < TD-Linux> could you specify the exact function call you want?
10:25 -!- sipa__ is now known as sipa     
10:26 < SopaXorzTaker> TD-Linux, point-by-scalar mutliplication
10:26 < SopaXorzTaker> multiplication*

10:26 -!- sipa [~pw@unaffiliated/sipa1024] has joined #secp256k1     
10:26 < SopaXorzTaker> with a known key, so that I can cross-check my methods
10:27 < SopaXorzTaker> I'd also like a recording of this done by a naive implementation
10:28 < SopaXorzTaker> (sqr - mul-sqr)
10:30 < TD-Linux> see also https://people.xiph.org/~tdaede/pics/sidechannel/
10:32 < TD-Linux> SopaXorzTaker, this is what a single secp256k1_ec_pubkey_create looks like https://people.xiph.org/~tdaede/pics/sidechannel//DS1Z_QuickPrint40.png
10:33 < SopaXorzTaker> TD-Linux, I need it over *specific* privkey
10:33 < SopaXorzTaker> better, a set of 2-3
10:33 < SopaXorzTaker> so that I can try to correlate
10:33 < TD-Linux> okay. I have also disabled blinding
10:34 < SopaXorzTaker> oh, you did this
10:34 < SopaXorzTaker> points
10:34 < SopaXorzTaker> will get my Rigol scope soon as a present from family
10:34 < SopaXorzTaker> that means fun with electronics and side-channel attacks
10:45 < TD-Linux> SopaXorzTaker, https://people.xiph.org/~tdaede/pics/sidechannel/secp_16_bits_hot.csv.gz
10:45 < TD-Linux> 16 rows, each is a different single bit '1' in the privkey
10:55 < SopaXorzTaker> uh, great
10:55 < SopaXorzTaker> thanks
