The U.S. National Institute of Standards and Technology Post-Quantum Computing project has been examining the pros and cons of nearly 70 proposed quantum secure algorithms. One proposed solution, Round5 (round5.org), boasts of “shortest key and ciphertext sizes” and holds a lead in performance and implementation. From a bandwidth, processing, and generally “size-matters” standpoint, Round5 may be the leader in NIST’s quest for a PQC algorithm solution.
