Post-quantum cryptography in government Aug. 2015 (Jan. 2016) “IAD will initiate a transition to quantum resistant algorithms in the not too distant future.” – NSA Information Assurance Directorate, Aug. 2015 Apr. Perhaps, after seeing quantum computers destroy RSA and DSA and ECDSA, Internet users will leap to the conclusion that cryptography is dead; that there is no hope of scrambling information to make it incomprehensible to, and unforgeable by, attackers; that securely storing and communicating information means using expensive physical shields to prevent attackers from seeing the information—for example, hiding USB sticks inside a locked briefcase chained to a trusted courier's wrist.
