US Government Escalates Push for Post-Quantum Cryptography
Federal agencies of the US government are expanding their calls for quantum computing resistant encryption methods. In effect, the National Institute of Standards (NIST) recently announced a request for public-key post-quantum algorithms. This action follows warnings from the National Security Agency (NSA) about the risks of potential quantum-based....

Bitcoin core developer Matt Corallo used a fresh Blockstream announcement this week to push back on a familiar line in the quantum debate: that nobody serious is working on post-quantum cryptography for Bitcoin. The immediate trigger was Blockstream’s preview of OP_SHRINCSVERIFY, but the broader point was that the work did not appear out of nowhere; […]
In a livestream broadcast titled “Post-Quantum Cardano,” ADA founder Charles Hoskinson laid out a roadmap for making the blockchain quantum-resistant. His remarks come amid rapid developments in quantum computing hardware, including breakthroughs from Microsoft and other tech heavyweights, as well as newly released US government standards for post-quantum cryptography. Hoskinson opened the session by highlighting […]
According to the U.S. Cybersecurity and Infrastructure Security Agency (CISA), while quantum computers are incapable of breaking public key encryption algorithms, public and private entities need to prepare for future threats against cryptography that is not quantum resistant. Most of today’s digital communications, including cryptocurrencies, leverage public key encryption and CISA believes when “quantum computers reach higher levels of computing power and speed, they will be capable of breaking the public key cryptography algorithms that are in use today.”

What happens to cryptography once quantum computers are everywhere? Will it still be possible to keep encrypted systems — like the Bitcoin network — secure? This week, Google addressed the question with a blog post titled, “Experimenting with Post-Quantum Cryptography,” which looks at how possible computing speeds in the future could compromise encryption, even today. Quantum computing, long a computer science holy grail, promises to increase processing speeds on data operations exponentially. Rather than coding data into binary bits that must be either “1” or “0,” a quantum computer would....
The way we think about encryption is starting to change, and NIST is working on making cryptography resistant to quantum computing. New cryptographic algorithms are needed, and Bitcoin developers need to start preparing for the future as well. Quantum Computing Threatens Cryptography Algorithms. Technology is advancing at an accelerated pace, and the....
