NIST has posted an update on their post-quantum cryptography program: After spending more than three years examining new approaches to encryption and data protection that could defeat an assault from a quantum computer, the National Institute of Standards and Technology (NIST) has winnowed the 69 submissions it initially received down to a final group of … Read More “Update on NIST’s Post-Quantum Cryptography Program” »

Factoring 2048-bit Numbers Using 20 Million Qubits

This theoretical paper shows how to factor 2048-bit RSA moduli with a 20-million qubit quantum computer in eight hours. It’s interesting work, but I don’t want overstate the risk. We know from Shor’s Algorithm that both factoring and discrete logs are easy to solve on a large, working quantum computer. Both of those are currently … Read More “Factoring 2048-bit Numbers Using 20 Million Qubits” »

Presidential Candidate Andrew Yang Has Quantum Encryption Policy

At least one presidential candidate has a policy about quantum computing and encryption. It has two basic planks. One: fund quantum-resistant encryption standards. (Note: NIST is already doing this.) Two, fund quantum computing. (Unlike many far more pressing computer security problems, the market seems to be doing this on its own quite nicely.) Okay, so … Read More “Presidential Candidate Andrew Yang Has Quantum Encryption Policy” »

Quantum Computing and Cryptography

Quantum computing is a new way of computing — one that could allow humankind to perform computations that are simply impossible using today’s computing technologies. It allows for very fast searching, something that would break some of the encryption algorithms we use today. And it allows us to easily factor large numbers, something that would … Read More “Quantum Computing and Cryptography” »

GCHQ on Quantum Key Distribution

The UK’s GCHQ delivers a brutally blunt assessment of quantum key distribution: QKD protocols address only the problem of agreeing keys for encrypting data. Ubiquitous on-demand modern services (such as verifying identities and data integrity, establishing network sessions, providing access control, and automatic software updates) rely more on authentication and integrity mechanisms — such as … Read More “GCHQ on Quantum Key Distribution” »

Interesting research on a version of RSA that is secure against a quantum computer: Post-quantum RSA Daniel J. Bernstein, Nadia Heninger, Paul Lou, and Luke Valenta Abstract: This paper proposes RSA parameters for which (1) key generation, encryption, decryption, signing, and verification are feasible on today’s computers while (2) all known attacks are infeasible, even … Read More “Post-Quantum RSA” »
