Vancouver, British Columbia--(Newsfile Corp. - February 24, 2026) - Quantum Secure Encryption Corp. (CSE: QSE) (OTCQB: QSEGF) (FSE: VN80) today announced two platform developments that further integrate its proprietary quantum-resistant entropy technology across its identity and migration readiness infrastructure.

These enhancements extend QSE's entropy foundation into authentication workflows and align its migration assessment capabilities with publicly available Canadian post-quantum migration roadmap guidance.

QAuth - Entropy-Enabled Identity Integration

QSE has integrated its proprietary quantum-resistant entropy into the QAuth identity and authentication platform, strengthening the entropy layer supporting secure single sign-on (SSO) workflows.

This integration:

• Embeds quantum-resistant entropy into identity-related key generation processes

• Reinforces session integrity and key lifecycle management within authentication flows

• Extends QSE's entropy architecture into access management infrastructure

• Positions QAuth among early identity platforms incorporating quantum-resistant entropy at the infrastructure level

By embedding entropy directly within identity workflows, QSE continues to operationalize its post-quantum infrastructure beyond assessment and into live authentication environments.

QPA v2 - Migration Enhancements Aligned with Canadian PQC Roadmap Guidance

QSE has also advanced Version 2 of its Quantum Preparedness Assessment (QPA) platform to incorporate structural elements aligned with publicly available Canadian government post-quantum migration roadmap principles, including the preparation and identification phases outlined in national guidance.

Enhancements include support for:

• Structured migration planning workflows supporting executive oversight and governance alignment

• Inventory-building processes to assist in identifying cryptographic dependencies across systems

• Risk prioritization methodologies, including consideration of long-term exposure scenarios such as "harvest now, decrypt later" (HNDL) threats

• Executive-level reporting visibility to support organizational accountability and planning

These enhancements are designed to help public and private sector organizations initiate structured post-quantum migration planning consistent with recognized best-practice frameworks. QSE's platform provides visibility and structured assessment capabilities but does not issue formal standards certification.

"These integrations reflect the evolution of our platform from entropy foundation to full-stack post-quantum infrastructure," said Ted Carefoot, CEO of QSE. "By embedding quantum-resistant entropy within identity systems and aligning our migration assessment capabilities with recognized guidance frameworks, we are helping organizations move from awareness to structured action."

These developments build upon QSE's prior announcements related to entropy services, enterprise engagements, and the continued expansion of its migration readiness platform.

QSE continues to align product development with emerging global post-quantum migration guidance as enterprises and governments prepare for long-term cryptographic transition.
