Quantum Security
The Post-Quantum Network is using the Extended Merkle Signature Scheme (XMSS) and NIST-approved Quantum Random Number Generation to secure its chain against quantum computer attacks and emerging AI threats.
Quantum computers can break 99% of today’s blockchain platforms, including popular cryptocurrencies like Bitcoin, Ethereum, Solana, Cardano, Ripple, and Polkadot. These platforms rely on traditional asymmetric cryptography-related schemes, including digital signature schemes, which quantum computers can break.
Before NIST announced the first four quantum-resistant cryptographic algorithms, the Post-Quantum Network chose its own algorithms back in 2018. NIST recommends one algorithm for quantum safety, but the Post-Quantum Network is using two primary algorithms for quantum-resistant signatures:
Extended Merkle Signature (XMSS) and Quantum Random Number Generation.
- Extended Merkle Signature (XMSS): A NIST-approved and IETF-RFC-specified post-quantum cryptography algorithm.
- Quantum Random Number Generation: A quantum random number generator (QRNG) generates streams of random digits by sampling a signal that contains sufficiently large quantum dynamic numbers.
Future-Proofing: These algorithms are designed with the future in mind. As quantum computing technology evolves, quantum-resistant algorithms will provide a foundation for secure communications and data protection.
