CypherShield, a product line of CypherEye Inc., develops a quantum-resistant security platform designed to protect existing IT infrastructure without requiring quantum computers or specialized hardware. The company's approach is based on computational impossibility rather than computational complexity, enabling encryption that is intended to remain secure against future quantum computing threats. The company offers three primary products: - CypherShield SDK: A complete ecosystem of SDK components that can be deployed in various configurations to augment existing IT security infrastructure. It covers key exchange (using a 3-pass transaction method of symmetrical and asymmetrical keys), encryption, key certification (endpoint authentication to prevent man-in-the-middle attacks), and digital signatures. - CypherComm: An SDK and white-labeled messaging stack that adds quantum-resistant security to VoIP, messaging, video conferencing, and email communications. - CypherIoT: A firmware update manager for resource-constrained IoT devices, providing secured exchange of firmware updates and configuration settings between IoT gateways and low-powered devices. The platform supports multiple data link types including IP, Bluetooth, NFC, RFID, and radio, and is designed to be low-latency and low-bandwidth. Use cases include low-powered IoT encryption, quantum-safe messaging, API connectivity, cryptocurrency/NFT security, and data-at-rest protection. The platform is designed to integrate with existing infrastructure rather than requiring replacement of current systems.
