I'm working with elliptic curve cryptography and have a generator point $G$ on the secp256k1 curve. For example, I can express a point as $5G$ (the result of multiplying the generator point by 5).

  1. Can the point $5G$ from secp256k1 be converted to an equivalent point on secp384r1? If so, how can I achieve this?

  2. Is there a direct method to translate a point from secp256k1 to an equivalent point on secp384r1?

I appreciate any guidance on how to manage the conversion of elliptic curve points while maintaining the integrity of my cryptographic operations.

I'll try to explain how this involves solving the discrete logarithm. The two curves you are looking at have NOTHING to do with each other.

Therefore the only way you could conceivably think of converting from one to the other is start with $kG$ in Curve 1, solve DL to get $G$ and then pick a generator $G'$ in Curve 2, and compute $kG'$ in Curve 2.
