If we have two elliptic curves $E$ and $E'$ and the points of both elliptic curves are same. Then all the points of $E$ map to all the points of another elliptic curve $E'$.

For example $E$ has seven points and $E`$ also have seven points then would isogeny make this possible?

Is the reverse $r$ possible by dual isogeny mapping? In other words, could all the points of $E'$ map to all the points of $E$?

  • $\begingroup$ I've tried my best to fix the question, but it is likely still unclear. I've translated "Saveen" to "seven", presuming that's what was meant. Please reread your question or show it to a friend before posting. $\endgroup$ – Maarten Bodewes Mar 13 '19 at 22:53
