I don't understand what the dot notation is. Is it like a multiplication operation or an addition operation or what? and how is that related to the Elliptic Curve Discrete Logarithm Problem? For example, this site is explaining an example of dotting two points on the Elliptic Curve

    It runs out the point addition! It is based on the geometric tangent and chord ( correction, it is chord) – kelalaka Mar 01 '21 at 15:48

    The tangent and chord rule and its relation to point additon to form a group is a long process to talk about ( especially the associativity). You can read it in a good book like Washinton's book. The ECC rely on the hardness of the DLog and for this, we need the scalar multiplicaiton as in the answer. – kelalaka Mar 01 '21 at 16:26
  • The nice article motivating the question uses cdot (in letters) to denote point addition on an Elliptic Curve, and is about explanation how that works. I can't find any other source with that notation. It's commonly used $+$, and the article only uses another notation to distinguish point addition on the Elliptic Curve group from addition in the underlying field (I use $\boxplus$ to that effect here). – fgrieu Mar 02 '21 at 06:05
