Qrypt Extends Quantum-Secure Gateway for AI Workloads with NVIDIA BlueField-4 DPUs

NVIDIA BlueField-3 solution available now for customer testing with SHI

WASHINGTON--(BUSINESS WIRE)--Following the successful launch of its Quantum-Secure IPsec Gateway capability on NVIDIA BlueField-3 DPUs, Qrypt today announced support for the newly unveiled NVIDIA BlueField-4 DPU. Additionally, Qrypt has also unveiled a partnership with SHI, a global IT solutions provider, to make the BlueField solution available for testing today.

Since debuting its technology with BlueField-3 DPUs, Qrypt has expanded deployments across AI data centers and high-security networks, achieving measurable advances in quantum key management efficiency and data protection.

Unlike traditional encryption systems that rely on key transmission over potentially imperceptible channels, Qrypt’s distributed model synchronizes identical encryption keys at multiple endpoints using quantum entropy—no keys ever traverse the network. By eliminating this legacy architecture and complexity of PKI infrastructure such as establishing/re-establishing a secure connection each time with network impact, Qrypt not only removes a major cybersecurity attack vector but also reduces connection latency and operational overhead, delivering faster and more scalable performant encryption. The solution also adheres to CNSA 2.0 compliance standards.

The result is instant, compliant, and unbreakable encryption that’s immune to the risk of “Harvest Now, Decrypt Later” ensuring the long-term confidentiality of AI data in motion and at rest.

SHI has built an AI sandbox environment, with Qrypt’s quantum secure gateway capabilities in its Customer Innovation Center (CIC) Lab. Whether customers want to understand how certain integrations can improve existing processes, obtain hands-on experience with new technology, or explore unconventional ideas, the Qrypt BlueField solution is available for immediate customer testing.

“Our collaboration with NVIDIA lays the foundation for broader quantum-secure innovation,” said Kevin Chalker, CEO of Qrypt. “As AI systems increasingly depend on data from the edge for inference and control across cloud-based GPU data centers, the need for stronger security guarantees has never been greater. We’re proving that encryption built for the quantum era can integrate seamlessly with existing infrastructure while scaling securely to the edge without performance tradeoffs.”

By leveraging the NVIDIA DOCA framework, the Qrypt integration has the ability to achieve full hardware offload while maintaining line rate IPsec data-plane performance. The encapsulation, encryption, decryption, and decapsulation of user data, remains fully offloaded to the hardware while still maintaining full throughput networking operations.

DOCA will enable this integration to seamlessly apply to the newly released BlueField-4 DPU’s where Qrypt will focus on air gapped capabilities for highly critical government use cases.

NVIDIA BlueField-4 is an accelerated infrastructure platform for gigascale AI factories, delivering powerful computing, 800 Gb/s throughput, and features multi-tenant networking, AI runtime security, rapid data access, and high-performance inference processing.

Qrypt’s progress marks a critical step toward a global cryptographic infrastructure that’s immune to both classical and quantum threats. By leveraging virtualization, containerization, and highly distributed infrastructure, Qrypt removes single points of failure and enables indefinite data protection — a necessity for the AI-driven, data-intensive future.

The solution will be on display at the NVIDIA GTC Conference in Washington DC, October 28-29, 2025, Booth #I-26.
