Independent review validates Qastle's integration of Quantum eMotion's QRNG2 engine and alignment with NIST, OWASP, and PTES security frameworks
Monroe, Louisiana--(Newsfile Corp. - November 25, 2025) - Krown Technologies, Inc., developer of the Krown Network and the Qastle quantum-secured hot wallet, today announced the findings of a comprehensive security assessment of the Qastle application suite and its integration with Quantum eMotion's QRNG2 quantum entropy engine. The assessment confirms the validity, viability, sustainability, and operational robustness of QRNG2 within Qastle's key-generation and wallet-creation workflows.
The Qastle Security Assessment concludes that Qastle's end-to-end architecture-mobile apps, API layer, and browser extensions-has been designed and implemented with a strong focus on protecting private keys, safeguarding user data, and securing all transaction flows.
QRNG2: True Quantum Entropy at the Core of Qastle
Within Qastle, entropy for cryptographic material is sourced directly from Quantum eMotion's QRNG2 engine through a tightly integrated API workflow. Each time Qastle needs randomness for key creation, it issues a call to the QRNG endpoint to retrieve a truly non-deterministic quantum value, rather than relying on traditional pseudo-random generators. Every call is logged with timestamps, response status, and system state, and transient failures trigger controlled retries until a valid quantum value is obtained.
All QRNG2 interactions and related logs are stored in a containerized infrastructure that provides isolation, integrity controls, and traceability. This design allows Krown's engineering team to verify that quantum entropy was requested, received, and correctly applied in the wallet-generation process, providing strong assurance that QRNG2 is operating as intended and sustaining its performance over time.
"We set out to prove-not just claim-that Qastle is driven by real quantum entropy," said James Stephens, Chief Executive Officer of Krown Technologies, Inc. "This assessment validates that Quantum eMotion's QRNG2 engine is not only viable, but operationally robust and sustainable in live production conditions. Every wallet that Qastle generates is backed by true quantum randomness, documented with auditable logs, and aligned with the highest standards of modern cybersecurity."
Built on NIST, OWASP, and PTES Security Frameworks
The Qastle assessment was conducted using globally recognized security frameworks, including the NIST Cybersecurity Framework, the OWASP methodology, and the Penetration Testing Execution Standard (PTES). NIST's Framework provides structured guidance to help organizations identify, protect, detect, respond to, and recover from cyber threats, while OWASP and PTES together define rigorous approaches to application security testing and penetration testing.
For Qastle iOS and Android, the review addressed cryptographic implementations, secure storage of sensitive material, application hardening, transport-layer security, and resilience against tampering and reverse-engineering. For the Qastle API, the assessment focused on endpoint-level controls, authentication and authorization flows, input validation, rate limiting, and session management. The browser extensions were reviewed for permissions, data-access boundaries, and message-passing behavior to ensure least-privilege operation and safe interaction with both the local environment and Qastle's backend.
"From the outset, Qastle was engineered to be a security-first wallet," said Gareth Slaven, Chief Technology Officer at Krown Technologies, Inc. "This assessment confirms that our architecture, our use of QRNG2, and our operational processes align with NIST, OWASP, and PTES best practices. Just as important, it confirms that QRNG2 behaves flawlessly in our production stack-delivering reliable, quantum-grade entropy without compromising performance or user experience."
Validating Viability, Sustainability, and Operational Flow
Beyond point-in-time testing, the assessment emphasizes Qastle's ability to sustain secure operations over time. Detailed logging of QRNG2 calls, containerized infrastructure, and robust error-handling flows demonstrate that the integration is not only technically sound, but operationally resilient.
By combining quantum-grade entropy with layered application security, Qastle is positioned to operate securely at scale as the number of users, transactions, and supported assets continues to grow. This security posture helps Qastle address today's attack landscape while preparing for emerging quantum and classical threats in the years ahead.
Path Toward NIST Certification
With the successful validation of Qastle's security posture and the confirmed operational integrity of Quantum eMotion's QRNG2 entropy engine, Krown Technologies is now preparing for its next milestone: formal NIST certification. The assessment demonstrates strong adherence to NIST's Cybersecurity Framework principles, and Krown's engineering team has already initiated the internal mapping required for certification readiness.
This next phase will involve expanding Qastle's documented controls, strengthening audit trails, and engaging with certified NIST evaluators to validate the architecture against official standards for cryptographic modules, entropy sources, and secure application processes. The move positions Qastle-and the broader Krown Network-to become one of the world's first quantum-secured wallet environments aligned with formal federal standards for cybersecurity.
"Our goal is clear: we intend for Qastle to meet and ultimately achieve NIST-grade certification," said James Stephens, CEO of Krown Technologies, Inc. "This is a natural progression after the outstanding performance demonstrated in our QRNG2 integration assessment. We are building technology for a world that demands provable, measurable, and certified security."
