A technology and fraud prevention expert, Olawale Oladoja, has called on banks, fintech companies and enterprise organisations to urgently begin transitioning to quantum-resilient security architectures.

The cybersecurity analysts warned that delays could expose critical financial infrastructure to next-generation cyber threats.

Oladoja, who has over eight years of experience spanning Nigeria and the United Kingdom in fraud analytics, enterprise risk, and change management, said the global cybersecurity environment is moving toward a post-quantum transition phase where traditional encryption systems may no longer be reliable.

He explained that widely deployed cryptographic standards such as RSA and Elliptic Curve Cryptography (ECC), which currently secure online banking, digital identities and financial communications, are expected to become vulnerable once scalable quantum computers are achieved, particularly through quantum algorithms such as Shor’s algorithm that can factor large integers and break public key encryption systems.

According to him, this shift makes it necessary for organisations to begin immediate migration planning toward Post-Quantum Cryptography (PQC), especially lattice-based cryptographic systems.

Oladoja said quantum computing introduces what he described as a dual-risk environment where the same technology capable of dismantling existing public key infrastructure could also be used to build highly secure, next-generation fraud detection and intelligence systems.

He noted that fraud patterns are already becoming more complex, with increasing cases of synthetic identity fraud, deepfake-enabled social engineering, SIM swap attacks, account takeover schemes and large-scale investment scams targeting digital banking users across multiple platforms.

“Quantum computing is not a distant disruption; it is an inflection point in how digital trust will be built and maintained. Institutions that begin preparing now by integrating quantum-resilient architectures will define the future of secure digital finance,” he said.

The tech expert noted that without proactive adaptation, quantum computing could significantly amplify these threats by enabling far more advanced pattern recognition capabilities for attackers while simultaneously weakening the cryptographic foundations that protect financial transactions and sensitive data.

He explained that the future of cybersecurity will depend heavily on hybrid systems that combine classical computing with quantum-enhanced capabilities, where machine learning models are reinforced with quantum algorithms capable of analysing high-dimensional fraud patterns in real time, making detection systems significantly more adaptive and predictive than current frameworks.

Oladoja stressed that organisations must begin building crypto-agility into their digital infrastructure, allowing them to seamlessly transition between cryptographic standards without requiring full system overhauls.

He said this capability will be critical as global standards evolve and post-quantum algorithms become mandatory across regulated industries.

He also urged financial institutions to start assessing their cryptographic dependencies and preparing migration pathways through pilot implementations of quantum-safe systems, including hybrid encryption environments that combine classical security protocols with emerging post-quantum standards.

Oladoja added that regulators, technology vendors and financial institutions must work together to establish governance frameworks that ensure compliance with emerging quantum-safe standards.
