Latest Release of Phio TX Features Multiple Key Generation Methods for Crypto-Agility and a Future-Proof Migration Path to Quantum Safety
Quantum Xchange today announced at the 16th Annual Billington Cybersecurity Summit (booth #512) the general availability of Phio TX® version 4.5. The latest release of its award-winning, Post-Quantum Cryptography (PQC) network security solution enables commercial enterprises and government agencies to harden their existing networking infrastructure against Harvest Now, Decrypt Later (HNDL) attacks and implement the latest PQC standards for quantum-safe networking.
Phio TX has always supported standard key management protocols like Cisco’s Secure Key Integration Protocol (SKIP) and ETSI (QKD GS 014), often referred to as the EQKD standard, to enable drop-in integration without requiring configuration changes to existing networking devices. Version 4.5 extends this support with Quantum Key Distribution (QKD) interoperability – QKD key generation, hybrid key generation (PQC + QKD), and additional orchestration functionality for seamless integration between SKIP and ETSI protocols.
The differing protocols create operational complexity and limit deployment scalability between different quantum resilient implementations. No matter what method of quantum-safe networking an organization decides on – QKD, PQC or a hybrid strategy – Phio TX can easily support it, enabling network administrators to deploy quantum-safe networking solutions with enhanced availability, fault tolerance, and multi-protocol support.

“We are committed to helping organizations deploy a crypto-agile infrastructure that offers quantum-safe key distribution today and eases the on-ramp to QKD-level security if desired,” said Gene Savchuck, Chief Product Officer at Quantum Xchange. “A key design feature of Phio TX is that it is deployed as a mesh network. The ‘hive’ acts as intelligent middleware that normalizes protocol differences and provides unified key management services.”
To support flexible deployment options, Phio TX is available in multiple form factors: secure hardware, software, and a recently announced container version. Version 4.5 includes support for running containers on ARMv8, the 64-bit version of the ARM processor architecture and now uses the industry standard NETCONF protocol, providing telemetry data for monitoring container health.
Phio TX leverages a unique, out-of-band symmetric key distribution that delivers immediate and superior cybersecurity posture to any network environment. By supplementing native encryption with an additional key-encryption-key (KEK) transmitted independently of the data path, Phio TX makes existing encryption environments, and the data transmitted, impervious to quantum attacks and significantly more secure. For these reasons, Quantum Xchange was named a winner in SiliconANGLE’s 2025 TechForward Awards in the Security Tech: Quantum-Safe CLM and PKI category.
