WebAug 12, 2024 · I hope this blog post doesn’t instantly become obsolete due to new advances. To recall, there are now three preprints giving attacks on SIDH: An efficient key recovery … WebJul 6, 2024 · 4. SIDH is a key exchange algorithm, not a digital signature algorithm. The way SIDH works is each side generates a private, random value along with a corresponding public value. The public values are exchanged, and from this, a shared secret can be mutually calculated. No signing is involved.

Supersingular isogeny Diffie–Hellman key exchange (SIDH or SIKE) is an insecure proposal for a post-quantum cryptographic algorithm to establish a secret key between two parties over an untrusted communications channel.
