We pursued this long-standing open question of the cryptographic community to settle concerns about ECDSA, which is one of our most widely used cryptographic standards. Readers should take this as a fun closing chapter and the end of years of speculation. There is no action to be taken or things to do differently. Most researchers trusted the curves already. Enjoy. ECDSA is the most widely used elliptic curve cryptography standard. It was adopted by NIST in 2000 as part of the FIPS 186-2 Digital Signature Standard which lists a set of standard elliptic curves of varying sizes and security levels. For curves over prime and binary fields, the specifications published a “seed” parameter whose hash value is used to define the coefficient b of the curve. The provenance of these seeds has been a long-standing question, as they were provided by the NSA with no explanation or justification.

MENEZES Abstract. In August 2015 the U.S. National Security Agency (NSA) released a major policy statement on the need for post-quantum cryp tography (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 tim ing 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. “It is a riddle wrapped in a mystery inside an enigma; but perhaps there is a key.” —Winston Churchill, 1939 (in reference to the Soviet Union) 1. Introduction In August 2015, the U.S. government’s National Security Agency (NSA) released a major policy statement [44] (see also [14]) on the need to develop standards for post-quantum cryptography (PQC).
