Stands for: Supersingular Isogeny Key Encapsulation

A post-quantum candidate that was dramatically broken in 2022.

Supersingular Isogeny Key Encapsulation was a promising isogeny-based post-quantum scheme until a 2022 attack broke it on a laptop in about an hour - a cautionary tale in why the NIST process hedges across different mathematical families.
