A Lightweight Privacy Protection Blockchain Framework Against Quantum Attacks
Summary
Quantum computers (powerful machines that could break current encryption methods) threaten blockchain security because traditional cryptographic algorithms like RSA are vulnerable to quantum attacks. Researchers proposed LLPP (Lightweight Lattice-based Privacy Protection), a blockchain framework using lattice-based cryptography (a quantum-resistant mathematical approach) combined with double encryption to protect transactions and user privacy even against quantum-capable attackers, while reducing storage overhead by storing only 46-byte identifiers on-chain through IPFS (a decentralized file storage system).
Solution / Mitigation
The LLPP framework addresses the storage challenge of lattice-based cryptography by leveraging the InterPlanetary File System (IPFS) for off-chain storage, recording only 46-byte content identifiers on-chain while maintaining full verifiability. The framework achieves practical deployment with signing and verification latencies below 2 milliseconds.
