Google Experimenting with Crypto for the ‘Post-Quantum Era’
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....

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....
It is ‘deja vu’ all over again as Google prepares for a future that seems inevitable. Like the millennium bug of the late 90s, Practical Quantum Computing looks like the next big turn in this era of internet security and encryption. Preparing for Advanced Quantum attacks. The prevailing concern is that in the near future, personal information may not be so secure as hackers could employ higher level computing procedures, otherwise known as Advanced Quantum attacks to crack current encryption techniques. Considering the potential weakness of encryption which could make it vulnerable in the....
Some computer scientists say quantum computers are moving closer to reality and will cripple bitcoin’s encryption systems and doom bitcoin. Governments are investing aggressively in quantum computers, which are ultra powerful. Quantum computers, first theorized by physicist Richard Feynman in 1982, have promised a new era of computing. The theory has only recently translated into significant real-world advances, with NASA, the CIA and Google working on a quantum computer. Computer scientists now warn the machines will cripple existing encryption methods and destroy bitcoin’s technological....
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.”

The rapid pace of development may make quantum computers a reality by the end of this year. Computer Science is one of the rapidly advancing fields. The progression of Bitcoin mining hardware since the cryptocurrency’s inception in 2009 is a good example. Now, the next giant leap for computing is stated to be Quantum Computing and it may soon become a reality, or at least that’s what a leading science publication states. There have been instances in the past when people have expressed their doubts about the future of Bitcoin once quantum computers become a reality. But the community took....
