5.1.1 The Threat Posed by Quantum Computers to Cryptography
In 1994, Peter Shor, an American researcher, published an algorithm demonstrating that, once a sufficiently powerful quantum computer becomes available, it will be able to factor integers exponentially faster than the best known classical algorithms. This discovery poses a major threat to current asymmetric encryption protocols. Unlike classical key-establishment algorithms such as Diffie-Hellman, RSA...
