I have a question about ECC basedEC-based DLP.
I know that getting k$k$ is hard when kG$kG$ is known. (G$G$ is a generator)
Question.Question:
Is it still hard that getting kG$kG$ where x$x$ is known? (in here, kG=(x,y) $kG=(x,y)$)
or that or getting k$k$ where x$x$ is known?
I think the former is not computationally hard. Am I right?
Thanks
