Could Advanced Quantum Computing Pose A Risk To Bitcoin Security?
Rapid progress in quantum computing could pose a risk to certain types of bitcoin transactions. So how can we combat this risk?Rapid progress in quantum computing is predicted by some to have crucial ramifications in domains using public-key cryptography, such as the Bitcoin ecosystem.Bitcoin’s “asymmetric cryptography” is based on the principle of “one-way function,” implying that a public key can be easily derived from its corresponding private key but not vice versa. This is because classical algorithms require an astronomical amount of time to perform such computations and consequently....

Quantum computing is a form of computing based on quantum physics. Where classical computers rely on bits (zeros or ones) to make calculations, quantum computers use quantum bits (qubits) that leverage quantum mechanics to exist in a “superposition”: a combination of zero and one, with some ...
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....
IBM has announced the launch of its quantum computing service called IBM Q along with a developer API. Quantum computers are considered to the future of computing. IBM is one of the of companies that is currently involved in the development of quantum computers. The tech giant has made news by announcing its plans to build the first commercial quantum computing system. With the recent announcement, IBM has made a name for itself as the provider of some of the disruptive technological solutions. The quantum computing systems and services follow the company’s suite of products in the AI (IBM....
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....
Worried about security for your bitcoin in the face of quantum computing? According to computer researchers, there’s no reason to be. Some people assume that once quantum computing comes along modern encryption technologies will be outpowered. But experts are starting to posit that hash functions and asymmetric encryption could defend not only against modern computers, but also against quantum attackers from the future. Matthew Amy from Canada’s University of Waterloo proposes just this in a paper by the International Association of Cryptologic Research. Amy, and researchers from Perimeter....
