Daiwa and Deloitte Advocate Phased Approach to Post-Quantum Cryptography (PQC) Implementation

September 20, 2026

SiliconANGLE USA

Overview

Daiwa and Deloitte propose treating Post-Quantum Cryptography (PQC) implementation as a manageable migration program rather than a physics problem, enabling organizations to streamline the transition. As PQC migration progresses from discussion to deployment, it is crucial to test ready components while addressing unresolved dependencies. Given the involvement of budget, product, and governance aspects, even seemingly simple technical changes can take years, making a phased approach essential for successful adoption.

In Depth

Key Findings

Daiwa and Deloitte have articulated a strategic framework designed to help organizations successfully navigate the transition to Post-Quantum Cryptography (PQC). They propose reconceptualizing PQC implementation not as an intractable physics challenge, but as a manageable migration program with distinct, actionable steps, thereby accelerating practical adoption by integrating budgetary, product, and governance considerations.

Technical / Clinical Details

PQC involves new cryptographic algorithms engineered to withstand attacks from future, powerful quantum computers that could break current public-key encryption standards. Its implementation necessitates extensive modifications across IT infrastructure, impacting key management, protocol updates, and application redesign. Daiwa and Deloitte recommend a phased approach: identifying unresolved dependencies while progressively testing components that are ready for deployment. This strategy enables organizations to distribute risk, optimize resource allocation, and proceed with migration efficiently. It shifts the paradigm from an all-at-once overhaul to an iterative, risk-managed process, acknowledging the complexity inherent in securing vast digital ecosystems.

Background & Context

The rapid advancement of quantum computing has brought the “Crypto-Apocalypse” – the theoretical future where quantum computers render current encryption vulnerable – closer to reality. Organizations worldwide, guided by bodies like the U.S. National Institute of Standards and Technology (NIST) which is standardizing PQC algorithms, are now developing PQC migration plans. This transition transcends a mere technical upgrade; it demands comprehensive organizational strategy, significant investment, robust risk management, and synchronized efforts across entire supply chains. The involvement of leading financial and consulting firms like Daiwa and Deloitte provides critical guidance for the broader industry, highlighting the imperative nature of this cybersecurity evolution.

Strategic Significance & Outlook

PQC migration is a long-term undertaking, projected to span several years. This proposed framework offers a pragmatic and efficient roadmap for enterprises to undertake this transition. By adopting a phased approach, organizations can build resilience against future quantum threats without disrupting current business operations. This strategic guidance is expected to empower many businesses, particularly those handling sensitive data such as financial institutions, to strengthen their security posture and maintain the integrity of the digital economy in the quantum era.
