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. Introduction to post-quantum cryptography 3 • 1994: Shor introduced an algorithm that factors any RSA modulus n using (lgn) 2+o(1) simple operations on a quantum computer of size (lgn) 1+o(1) .
