Sealsq announces deployment of PQC technology to protect bitcoin wallets

SEALSQ (LAES) announced the deployment of its advanced post-quantum cryptographic technology to protect Bitcoin wallets from future quantum computer attacks. The company said, “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, 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 designed to withstand quantum attacks. These lattice-based algorithms ensure security against Shor’s and Grover’s algorithms, offering forward secrecy and unforgeable signatures.”
