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. some researchers provided the idea about post-quantum cryptography which refers to research on cryptographic primitives (usually public-key cryptosystems) that are not breaka‐ ble using quantum computers.
