Hasn't classical already severely crippled ECC because of some mathematical Assumptions that somebody came back in 2022 and Proved were wrong?

Hasn't classical already severely crippled ECC because of some mathematical Assumptions that somebody came back in 2022 and Proved were wrong?
- markusde 1y agoCould you link to any more information about this?
- kevindamm 1y agoWhich assumptions? ECDLP is still considered computationally hard, and ECC considered secure. There are invalid curve attacks and small subgroup attacks but that's a problem with key selection, not a fundamental problem with ECC. Do you have a citation?
- bitexploder 1y agoNot in general, no. It is still secure and used. There are of course attacks but those were not completely breaking
- cwmma 1y agoI believe you are thinking of "Supersingular isogeny Diffie–Hellman key exchange" or SIKE which is a post quantum encryption algorithm that was spectacularly broken a couple years ago. The math involves elliptical curves but it's different from the elliptical curve cryptography used in your browser.
