G7 Warns Quantum Threat Demands Action as Crypto Industry Weighs Fixes
The G7 Cybersecurity Working Group has issued a report warning that quantum computing poses a security and economic threat, urging organizations to migrate
Key takeaways
- The G7 Cybersecurity Working Group called quantum computing a security and economic threat to public and private organizations.
- Attackers can collect encrypted data today and decrypt it later if sufficiently powerful quantum computers emerge.
- Current quantum computers cannot break Bitcoin's cryptography.
- Bitcoin developers are considering post-quantum proposals including BIP-360 to support new signature schemes.
- Ethereum researchers are planning replacements for cryptographic components, including a proposal to rebuild the deposit contract.
The G7 Cybersecurity Working Group has issued a report warning that quantum computing poses a security and economic threat, urging organizations to migrate to post-quantum cryptography (PQC) immediately. Although the report does not explicitly mention cryptocurrency, the same public-key cryptography protects blockchain wallets. In response, Bitcoin developers are considering proposals like BIP-360, Ethereum researchers are planning cryptographic replacements including a rebuilt deposit contract, and the Solana Foundation has already tested post-quantum signatures on a test network.
The transition to post-quantum cryptography is deemed a key foundation to safeguard digital infrastructures.
In their words
“Although the exact timeline is uncertain, several recent advances suggest an anticipation of the development of quantum computers able to break widely used public-key cryptography mechanisms and threaten the security of digital infrastructures”
“To strengthen collective resilience and safeguard confidential data, supply chains, and critical systems, public and private organizations must jointly act now”
