A Riddle Wrapped in an Enigma by Neal Koblitz and Alfred J. Menezes – “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 muchspeculation concerning the NSA, elliptic curve cryptography (ECC), andquantum-safe cryptography. Our purpose is to attempt to evaluate someof the theories that have been proposed.”
