ECDSA signing vs generating public key I'm trying to understand the process of ECDSA signing. I already figured out the process of generating a public key out of a private key by multiplying the private key with G.

The equation for ECDSA signing is as follows: $S = k^{-1} (\text{hash} + dA * R) \pmod p$. What I'm trying to understand is the process of multiplying $dA$ (my private key) by $R$ ($x$ of public key generated from random private key). Is it a "simple" multiplication (such as 5*5 = 25) or the same way we multiply $k$ by $G$ to generate a public key?
Is it a "simple" multiplication (such as 5*5 = 10) or the same way we multiply k by G to generate a public key?


It's multiplication modulo the curve order.  For example, if dA = 9, R = 7 and p = 13, then dA * R = 9 * 7 mod 13 = 63 mod 13 = 11.
