Cryptography in the Quantum Era: How the McEliece Cryptosystem May Be Used to Develop Quantum-Resistant Cryptography

If quantum computing becomes feasible, many popular cryptographic schemes, such as RSA, Diffie-Helman, and methods using elliptic curves will no longer be secure. This paper explores code-based cryptography, specifically looking the McEliece cryptosystem, as well as the more recent Classical McEliece cryptosystem, which was proposed to the National Institute of Standards and Technology (NIST) as a potentially quantum-secure algorithm.
