Why is QSN critical for the financial sector?
With quantum computing advancing rapidly, the current encryption methods may soon be rendered insecure.
Today’s security standards are largely based on the idea that classical computers cannot perform the calculations needed to crack encryption keys in a practical timeframe. Research suggests that quantum computers, which can perform these calculations significantly faster, will be able to break current encryption methods in a far shorter space of time.
Financial data is particularly sensitive and, in many cases, remains valuable for years or decades. ‘Harvest now, decrypt later’ attacks involve malicious actors intercepting protected communications today and decrypting them when sufficiently capable quantum computers become available. This creates significant risk for financial institutions that must protect transactions, customer data and other sensitive information over the long term. The importance of protecting long-life data and preparing for the quantum-safe transition is a recurring theme within Toshiba’s QSN positioning.
Toshiba Quantum-Safe Networking (QSN) provides financial institutions with a scalable foundation for protecting critical communications, financial transactions and sensitive data against both current and future threats. By bringing together technologies such as Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) within a unified platform, QSN supports a resilient and crypto-agile approach to security that can evolve as technologies, standards and threats continue to change.
How does Toshiba's QSN platform work?
Toshiba Quantum-Safe Networking (QSN) provides a unified platform for protecting critical communications, financial transactions and sensitive data against both current and future threats. Designed to integrate with existing communications infrastructure, QSN brings together quantum-safe technologies within a scalable architecture that can evolve as requirements change.
Technologies including Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) can be combined within the platform to support a resilient and crypto-agile approach to security.
How do Toshiba’s QSN platform protect against ‘harvest now, decrypt later’ attacks?
Harvest now, decrypt later’ attacks are already a reality. Adversaries can capture and store sensitive encrypted data today, with the intention of decrypting it in the future when sufficiently capable quantum computers become available. Financial records, intellectual property, government information and other long-life data may remain valuable for years or decades, making them particularly vulnerable to this threat.
The quantum-safe transition has already begun, and organisations must prepare now to protect critical communications and sensitive data. The migration deadline is determined not by when quantum computers become capable, but by the lifetime of the data being protected and the time required to complete the transition.
Toshiba Quantum-Safe Networking (QSN) provides a scalable foundation for this transition, enabling organisations to introduce quantum-safe protection into existing networks and evolve as requirements change. By supporting technologies such as Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) within a unified platform, QSN helps organisations protect long-life data against both current and future threats
