This past week, cryptologists from Belgium and The Netherlands released a report on a post-quantum computing algorithm promising quantum resistance. The claim is the algorithm provides a non-interactive key exchange while similar in construct to common elliptic curve cryptosystems (ECCs). This commutative, super-singular elliptic-curve, is touted as being able to be “dropped-in” to replace instantiations of quantum-vulnerable ECCs while maintaining quantum-resistant security schemes. Read the researcher’s report on this scheme dubbed “Commutative Super-singular Isogeny Diffie-Hellman” (CSIDH).


Quantum-resistant cryptosystems are being developed; the “drop-in” variety.
