Post-Quantum Cryptography

Quantum computing is expected to challenge many of the public-key cryptographic algorithms currently used to protect digital communications, identities, transactions and connected devices. Organizations must begin preparing today, particularly where sensitive data must remain protected for many years or where deployed devices have long operational lifecycles.

Through WISeKey’s Root of Trust and SEALSQ’s semiconductor and post-quantum technologies, organizations can integrate quantum-resistant security across hardware, software, networks and cloud environments. The portfolio supports standardized post-quantum algorithms, secure key generation and storage, digital signatures, encryption and cryptographic lifecycle management.

Our crypto-agile approach helps customers progressively migrate from conventional cryptography to post-quantum security without disrupting existing operations. Solutions can support hybrid architectures combining established and post-quantum algorithms during the transition period.
