- Google warns quantum machines may break crypto security sooner than expected.
- New estimates show lower resources needed to attack elliptic curve systems.
- Industry must shift to post-quantum cryptography before 2029.
Google has expanded its efforts to prepare for the quantum era. The company has worked on post-quantum cryptography since 2016. Its latest whitepaper highlights new risks for current security systems. Quantum computers can break the encryption much faster than previously believed.
Most cryptocurrencies and safe sites use elliptic curve cryptography. This is the cryptography used to protect digital transactions and other data. Quantum computers can compromise this security. Google claims this can be done with fewer qubits and operations.
This is the challenge facing the global technology sector. Google is urging early action to address this. They recommend blockchain and financial sites take early steps. Delaying this can leave huge security gaps. They link this to the trust users can place in these sites and the economy.
Google Study Updates Quantum Attack Estimates
The research also introduces new quantum attack estimates. The research mainly deals with the elliptic curve discrete logarithm problem. This problem allows for the development of several contemporary encryption techniques. The engineers at Google have developed optimized quantum circuits for executing Shor’s algorithm efficiently. The optimized circuit has less than 1,200 logical qubits and 90 million operations.
Another circuit has less than 1,450 logical qubits and fewer operations. The optimized circuits have greatly reduced hardware demands. The research implies that a powerful quantum computer can breach encryption in a matter of minutes. The computer would require less than 500,000 physical qubits.
This is a significant reduction from previous estimates. It is a sign of progress in quantum research. Google links this to advancements in its own quantum hardware. The company also observes that hardware advancements continue. This brings quantum threats closer. Experts believe that the threats are closer in time.
Google Urges Shift to Post-Quantum Cryptography
Google recommends adopting post-quantum cryptography. This will ensure the security of systems against quantum-based attacks. This method already exists, but it will take time to fully adopt it.
The company has been working with government agencies to ensure the results are shared appropriately. It has also been working with other companies, like Coinbase, Stanford Institute for Blockchain Research, and Ethereum Foundation. This ensures the security of the systems and can be adopted before 2029.
The company has proposed a controlled disclosure method, which can be achieved through zero-knowledge proofs. This ensures that the information shared does not fall into the wrong hands, and the systems remain informed.
The company has proposed some measures to be taken. It recommends that users should not use the same addresses for their wallets. This can ensure the security of the system during the transition. The report concludes that early preparation will determine the future.
