Castle Shield Holdings, LLC Adds Post-Quantum Cryptography (PQC) Support to Its Typhos® Communications App for Audio/Video Calls

SCOTTSVILLE, Va.--(BUSINESS WIRE)--Castle Shield Holdings, LLC., a leader in Zero Trust and cybersecurity solutions, today announced that its Typhos^® Secure Communications mobile solution now supports post-quantum cryptography (PQC) algorithms selected by the National Institute of Standards and Technology (NIST) for audio and video calls. Typhos^® is the industry’s first end-to-end PQC software-based solution uniquely designed to protect encrypted chat and audio/video communications using quantum-resilient asymmetric algorithms. The Typhos^® crypto-agile PQC solution offers companies, organizations, and consumers a secure, comprehensive, and convenient messaging solution that protects privacy against potential threats for today and tomorrow.

In October 2022, we announced PQC asymmetric encryption support for Typhos^® chat messages and attachments. At that time, Typhos^® audio/video features used classical Elliptic Curve Diffie-Hellman (ECDH). Typhos^® now supports PQC asymmetric encryption for audio/video calls as well. With this update, all Typhos^® features are protected with end-to-end PQC encryption.

The Typhos^® standard configuration is Kyber1024; however, other Kyber and Dilithium variants are available to enterprise users upon request. Typhos^® is currently the most secure messaging and communications app available today. Typhos^® is a Software as a Service (SaaS) solution, although companies can host the solution themselves on-premises or via the cloud for additional data privacy.

“While current quantum computers cannot break widely used cryptography schemes like RSA or ECDH, companies should start implementing quantum-safe solutions as soon as possible. Any data with a multi-year lifespan could be harvested today and decrypted in the future. It behooves companies and individuals who care about their data privacy to start implementing quantum-safe encryption today,” said Dr. Milton Mattox, CTO at Castle Shield.
