Sealsq: SEALSQ Corp Unveils Quantum-Resistant Cryptography with QS7001 to Secure Bitcoin Wallets Against Quantum Threat

SEALSQ Corp. announced the deployment of its advanced post-quantum cryptographic (PQC) technology to protect Bitcoin wallets from future quantum computer attacks. Integrated into the cutting-edge QS7001 secure element, this solution marks a significant step in ensuring the long-term security of blockchain assets in a quantum era. Bitcoin wallets rely on elliptic curve cryptography (ECC), specifically the secp256k1 curve, to generate public-private key pairs. While secure against classical attacks, quantum computers using Shor's algorithm could potentially derive private keys from exposed public keys, compromising wallets when addresses are reused or transactions are broadcasted. This vulnerability threatens the integrity of decentralized finance as quantum computing advances. SEALSQ addresses the threat with a robust PQC stack based on CRYSTALS-Kyber and CRYSTALS-Dilithium, NIST-standardized algorithms (FIPS 203 and ML-DSA) designed to withstand quantum attacks. QS7001 Secure Element: Hardware-Backed Security: SEALSQ's PQC algorithms are embedded in the QS7001 secure elements, a tamper-resistant chip optimized for resource-constrained environments like hardware wallets and IoT devices. The QS7001 enables: Secure storage of post-quantum private keys. Efficient quantum-resistant signing and key exchange operations. Hardware-rooted trust with low power consumption, ideal for cold wallets and embedded systems. Migration Framework for Blockchain Developers: SEALSQ offers a practical migration path for Bitcoin wallet developers and custodians: Hybrid Cryptography: Supports a dual-stack approach (ECDSA + Dilithium) for backward compatibility during the transition to PQC. Quantum-Safe Addresses: Introduces a new address format for quantum-resistant wallets, ensuring future-proof security. Key Rotation Tools: Facilitates secure migration of legacy keys to PQC-protected keys, minimizing exposure risks.
