Standardization Requires Stability: NIST’s Post-Quantum Algorithm Candidate’s Future Uncertain

…Researchers from the University of Bristol on Monday proposed an attack on SIKE they say “significantly reduces” the security of SIKE by solving it with torsion… 

…Uncertainty surrounds [the] cracked post-quantum cryptography algorithm being considered by the National Institute of Standards and Technology, now that researchers have potentially discovered a second attack method…

…NIST won’t make a final decision on whether to standardize any of its four Round 4 candidates, including the Supersingular Isogeny Key Encapsulation (SIKE), for 18 to 24 months, giving the team behind it time to find fixes if it chooses…
