[G7 Urges Immediate Transition to Post-Quantum Cryptography, Bitcoin, Ethereum, and Solana Developers Have Tested Defense Solutions] Odaily Planet Daily News: The G7 Cybersecurity Working Group stated in its latest report that quantum computing poses both security and economic threats to public and private institutions. Relevant organizations should immediately begin transitioning to post-quantum cryptography (PQC). The working group noted that the migration process could take years, and attackers are already capable of collecting and storing encrypted data to decrypt it once sufficiently powerful quantum computers emerge. Quantum computing may also compromise digital signatures, leading to identity theft and exposing businesses and their supply chains. The report did not mention cryptocurrencies, but similar public-key cryptography is used in blockchain wallets and transaction authorization. Currently, quantum computers are unable to break Bitcoin cryptography, but developers are considering post-quantum solutions such as BIP-360. Ethereum researchers plan to replace several cryptographic components used in accounts, validators, and applications. The Solana Foundation has tested post-quantum signatures on its testnet and introduced optional hash-based vaults. The G7 working group also urged governments to support related research, public-private partnerships, and national PQC strategies. (Decrypt)
