How secure is elliptic cryptography from quantum computers?

Question

Cryptography

As far as I understand, the appearance of a more or less normal quantum computer will help to easily crack asymmetric algorithms, where the keys were large prime numbers. RSA, Diffie-Hellman, etc. And what about this elliptic cryptography that I don't understand ?

Z.Y.

I would be grateful for good, preferably Russian-language articles on the topic of post-quantum cryptography (including about key exchange)

Answer 1

Elliptic cryptography, under the parameters currently used, is much less resistant to quantum algorithms than RSA. RSA, by the way, is considered quite stable, 4096 qubits are required to crack 2048-bit RSA.

Answer 2

If, as you say, quantum computers appear, then the so-called quantum cryptography will appear with them, by the way, the concepts of such data encryption are already being developed in Korea.
