QuSecure ran field tests of its post-quantum cryptography platform, QuProtect R3, on US Army tactical systems during the Project Convergence exercises. The solution was used to secure communications against future quantum attacks in tactical networks, and to manage cryptography and detect which algorithms were in use. According to QuSecure, real service members participated in the testing under conditions that closely mimicked real-world deployment.

What happened

The company put QuProtect R3 through its paces directly in the US Army’s tactical environment as part of Project Convergence. The goal: deliver quantum-resistant communications and centralized management of cryptographic tools across both networks and individual nodes.

How QuProtect R3 was used

The platform tackled two main jobs: providing quantum-safe communications within tactical networks, and giving operators tools to manage cryptography—including detecting which algorithms were running. This approach is designed to cut the risk of interception and streamline oversight of cryptographic protocols in use.

Readiness level and test conditions

After the field trials, QuProtect R3 achieved Technology Readiness Level (TRL) 7. QuSecure says the tests involved active-duty personnel and took place in scenarios as close to real-world conditions as possible.
