Quantum computers still not a practical threat to AES-128 symmetric encryption

Even if quantum computing advances, symmetric-key encryption such as AES-128 is not a realistic target for attacks, a claim said. Cryptography engineer Filippo Valsorda, who maintains the Go programming language’s cryptography standard library, said quantum threats should distinguish between public-key and symmetric-key cryptography. He said Shor’s algorithm threatens asymmetric systems such as RSA and ECDSA, while Grover-based attacks on AES-128 remain extremely costly. He also urged focusing resources on replacing Shor-vulnerable public-key cryptography.

Bitcoin private key could be stolen in 9 minutes after public key exposure, Google quantum paper shows

A paper by Google Quantum AI outlines specific quantum-computing attack scenarios targeting Bitcoin’s secp256k1 elliptic-curve cryptography. It estimates that after a Bitcoin public key is exposed, a quantum computer could take about 9 minutes to calculate the corresponding private key, aided by precomputing fixed curve parameters. The paper describes two quantum circuit designs requiring 1,200 to 1,450 logical qubits and tens of millions of T gates, with fewer than 500,000 physical qubits.
