Microsoft and Google both project that a workable quantum computer capable of decrypting the Rivest–Shamir–Adleman (RSA) public-key cryptosystem, used for secure data transmissions, may be achievable by 2025. In the meantime, the crypto community has been trying to prepare for the transition to “quantum-resistant” algorithms — that is, algorithms that are secure against an attack by a quantum computer. This eBook examines some of the likely candidates for those algorithms and how they’ll be fitted into the Transport Layer Security (TLS) protocol that we all use today with HTTPS.
