Episode Synopsis

NIST's round four post-quantum crypto candidate SIKE (Supersingular Isogeny Key Encapsulation) has been defeated and is now out of consideration. In this episode we explain isogeny cryptography, why NIST is seeking additional candidates, and why failures of this kind are expected and healthy for PQC.
