Stay Alert to Crypto Wallets Protection from Quantum Computer Attack

Cybersecurity experts foresee quantum computers could be advanced enough to break through the Great wall of Cryptographic security within a decade. The application of digital signature to access financial accounts could be risky to be attacked by quantum computer hacking, CNBC reported Thursday.

Cybersecurity experts indicate that most world financial services are using asymmetric cryptography. Individuals generally use public-private key pair to access digital services, such as email or crypto wallets, by using the public-private key pairs and verified by a digital signature to correspondent accounts.

However, the technique of digital signature, i.e. Elliptic Curve Digital Signature Algorithm, could be risky, allowing hackers with quantum computing to forge the digital signature and subsequently empty crypto wallets.

Although the technology of quantum computers is still developing, experts predict quantum computers could be advanced enough to break the cryptographic security of digital assets within a decade, including Bitcoin wallets.

“Every single financial institution, every login on your phone. It is all based on asymmetric cryptography, which is susceptible to hacking with a quantum computer,” Fred Thiel, CEO of cryptocurrency mining specialist Marathon Digital Holdings, said.

However, cryptographer experts said that they do not worry too much about the quantum hacking of Bitcoin wallets as it still has time to well-prepared. Castle Island Ventures founding partner Nic Carter pointed out that quantum breaks would be gradual rather than sudden:

 “It wouldn’t be something that happens overnight; We would have plenty of forewarning if quantum computing (were) reaching the stage of maturity and sophistication at which it started to threaten our core cryptographic primitives.

Yet, it is still running out of time if the institutions and the public ignore protecting their crypto assets. Thiel said some countries, for example, China, could be able to crack wallets on the blockchain if the government owns a quantum computer.

Thiel further explained that The National Institute of Science and Technology (NIST) in the U.S. has been working on a new standard for encryption to strengthen quantum-proof.

According to the coverage from CNBC, the first standard, the quantum-safe crypto algorithm, is expected to meet the public by 2024 before quantum computers can break bitcoin’s cryptography. Groetker said that once the newly standardised post-quantum secure cryptography is completed, a mass migration of assets will begin.

“Everyone who owns Bitcoin or Ethereum will transfer [their] funds from the digital identity that is secured with the old type of key, to a new wallet, or new account, that’s secured with a new type of key, which is going to be secure,”

Still, hackers could target some traditional accounts and become increasingly insecure if no appropriate and proactive upgrades by using weaker keys. Institutions are recommended to lock down all old-type cryptography and give owners a limited way to access it to deal with cybersecurity upgrade risks.

Last month, at least a hundred Instagram users from Malta were reportedly attacked by hackers. Criminals were demanding that users pay Bitcoin if they wished to regain access to their accounts.  The hackers are allegedly Turkey-based, and this cybercrime has been happening for a few months

Is Quantum Computing Placing Bitcoin’s Future in Jeopardy? Quantum Expert Andrew Fursman on Future of Crypto

Quantum computing expert Andrew Fursman is convinced quantum attacks in the future will pose a threat to the security of Bitcoin (BTC).

In a video, Fursman highlights that the massive computational potential of quantum machines could be capable of compromising Bitcoin’s security.


“It’s mathematically proven that if you have a device that looks like the kind of quantum computers that people want to build, then you will be capable of decrypting this information significantly better than could ever be possible with classical devices.”

Fursman argues that regardless of when quantum computers come of age, a solution needs to be found.

“Whether quantum computers come out tomorrow or in five years or in ten years, they are capable of being cryptographically useful. Those devices are going to be capable of doing something that you might not want if you are somebody that’s keeping a secret…

So it’s worth kind of getting into what are the different ways that the blockchains rely on cryptography, and which of those are specifically relevant to the things that quantum computers of the future might do. And how much is that really a problem for people today, versus not a problem at all? And what things are maybe not a problem yet but we might want to be thinking about working on? Better to be safe than sorry.”

While Fursman says that quantum machines may place Bitcoin’s cryptography in jeopardy, he notes that it will not happen anytime soon.

“We might need actually significantly more qubits (quantum bits, or a unit of quantum information) than are currently available. And like I sort of alluded to, we might be at the point where the largest computers that we are building today end up really becoming the foundation of one logical qubit for one of these large devices…

So if we need a thousand times more qubits then we might have in a few years, you sort of have to be thinking about the growth of these things from both the error correction standpoint and the number of logical qubits that you need to go forward…

And I should say some people even put the number as high as millions that you might need. So we are definitely, we are not right around the corner from this. It’s not going to happen next week.”

IBM Building -459 Fahrenheit Fridge to House World’s Largest Quantum Computer

IBM is designing a massive “super-fridge” with the idea that it could house a record-setting quantum computing system. Codenamed “Goldeneye,” the fridge will be 10-feet tall and 6-feet wide, according to Jay Gambetta, an IBM fellow and the vice president of IBM Quantum. Says the executive, “Our team has designed this behemoth with a million-qubit […]
