Post-Quantum Cryptography, Primer Blog. PQC, or post-quantum cryptography, is becoming a more familiar term amongst cryptographic and cybersecurity communities. With the media-blitz of the coming quantum computing apocalypse, anyone involved in cybersecurity should add to their background some hows and whys for using post-quantum computing cryptographic methods. Though our Transport Layer Security (TLS) and Secure Socket Layer (SSL) methods are okay, today, any organization or nation-state hoarding data encrypted with these methods will likely be able to decrypt today’s data on Q-Day – the day when it is shown that quantum computers can break such cryptographic methods in short order. Having some knowledge of Shor’s Algorithm, Grover’s Algorithm, lattices, isogenies, and elliptic curve cryptography is wise. As suggested, if you deem the need for PQC for your organization is now, “get in touch with your friendly neighborhood cryptographer. Everyone else ought to wait until NIST has finished its standardization process.” For the Qubit Report, we recommend getting in touch with your neighborhood cryptographer or at least in touch with your quantum computing side…Because Quantum is Coming.
