“A RIDDLE WRAPPED IN AN ENIGMA \ In August 2015 the U.S. National Security Agency (#NSA) released a major policy statement on the need for post-quantum #cryptography (PQC). This announcement will be a great stimulus to the development, standardization, and commercialization of new quantum-safe algorithms. However, certain peculiarities in the wording and timing of the statement have puzzled many people and given rise to much speculation concerning the NSA, #elliptic_curve_cryptography (#ECC), and quantum-safe cryptography. Our purpose is to attempt to evaluate some of the theories that have been proposed.”
