Problem
Organizations face increasing threats from cyberattacks, especially as quantum computing advances, rendering current encryption methods vulnerable. Protecting sensitive data and critical infrastructure requires a new approach to key distribution that is resistant to both classical and quantum computing attacks.
Solution
Quantum Bridge provides quantum-safe cybersecurity solutions, including a Symmetric-Key Distribution System (SDS) that protects data from evolving cyber threats. The company's Distributed Symmetric Key Establishment (DSKE) protocol, combined with Post-Quantum Cryptography (PQC) and Quantum Key Distribution (QKD), delivers high-entropy cryptographic keys. This technology ensures secure data exchange and processing, enabling organizations to maintain robust security in an evolving digital landscape. Quantum Bridge's solutions are designed to be crypto-agile, scalable, and interoperable with existing network infrastructure.
