S calculate From (priv_publickey _XY ,nonce_publickey_XY ,and Message(z))
hi,
example data:
priv_publickey _XY = px: 0xbb6c1de01f36618ae05f7c183c22dfa8797e779f39537752c27e2dc045b0e694 py: 0x2f8af53270bf045f2258834b6dad7481ad6fca009d80f5b54697b08d104fc7b3
nonce_publickey_XY = px: 0xcabc3692f1f7ba75a8572dc5d270b35bcc00650534f6e5ecd6338e55355454d5 py: 0xafa7746c07a124cb59e190f00955952a7329591b805c4d9d04d34abe8a803a74
Message(z)) = 0x9b076ad2fe6b2ce63acf4edf7fc82d5152d3c8bffb36b944da7a1cce038f544a

S output need using S calculate From
priv_publickey _XY ,nonce_publickey_XY ,and Message(z)S = 0xf65bfc44435a91814c142a3b8ee288a9183e6a3f012b84545d1fe334ccfac25e
My question is how to calculate the
S value using only d publickey _XY, k publickey _XY, and z.
I understand the S calculation formula: s = (z+x*r)/k
but I need
another method to get S, s = (z+priv_publickey _XY*r)/nonce_publickey_XY # my idea this is right
My English is a little bit
Edit:
share a possible idea.
