CardLab Aps explores the risks associated with quantum computing and presents sustainable solutions to maintain online security. Quantum computing, once a theoretical concept, is quickly becoming a reality with the potential to transform various industries. However, one area of major concern is its impact on online security.

Quantum computers, due to their immense processing power, are capable of solving complex problems much faster than classical computers. While this presents numerous opportunities, it also creates significant risks for online security, as quantum systems may be able to crack the cryptographic algorithms that protect our digital infrastructure.

In this article, CardLab examines the imminent threats posed by quantum computing and investigates effective ways to counter these risks. Specifically, we focus on offline biometric authentication devices, which offer a secure, sustainable solution for identity verification and data protection.

Incorporating offline components adds a layer of complexity that makes it difficult for quantum computers to break cryptographic algorithms, which are built on mathematical logic. This added security layer could help mitigate quantum threats to online security and safeguard critical infrastructure.

The Threat of Quantum Computing to Cryptography

Modern cryptography depends on the complexity of certain mathematical problems, such as prime factorization, to secure data. Currently, widely used cryptographic algorithms like RSA and ECC (elliptic curve cryptography) assume that solving these problems takes too long for classical computers. However, quantum algorithms like Shor’s algorithm could break these encryption systems by exponentially reducing the time needed to solve them.

This means that RSA encryption could be compromised in just minutes or seconds by quantum computers, potentially exposing sensitive data such as financial transactions, personal identities, and classified information, or even enabling bad actors to hijack accounts or take control of critical infrastructure.

State Actors and Quantum Computing

While private enterprises and academic institutions lead quantum research, governments are the most significant threat when it comes to exploiting quantum technology for cyberwarfare. When quantum computing becomes fully mature, it could give governments the ability to bypass almost all existing encryption, putting everything from military secrets to citizens' personal information at risk.

State-sponsored hacking activities have been on the rise, with governments targeting other nations' critical infrastructure, intellectual property, and sensitive data. With the advent of quantum computing, these threats will intensify, as state actors will gain access to unprecedented cyber capabilities.

Governments could use quantum computing to manipulate elections, compromise communications, attack financial systems, or disrupt energy grids, among other activities. Organisations relying on outdated cryptographic methods will be vulnerable to these advanced threats.

Preparing for Quantum Threats with Post-Quantum Cryptography

To combat this looming danger, researchers are developing post-quantum cryptography (PQC), which is designed to resist quantum-based attacks. PQC relies on mathematical problems that quantum computers struggle to solve. However, cryptographic systems are vulnerable to logic-based attacks, and the race between hackers and researchers is ongoing.

Institutions like the National Institute of Standards and Technology (NIST) are working on standardising post-quantum cryptographic algorithms. However, full implementation of PQC will take years, meaning organisations need practical solutions now to protect their systems as these technologies evolve.

The Role of Offline Biometric Authentication Devices

CardLab believes that a key, sustainable solution to counter quantum threats is the use of offline biometric authentication devices. These devices do not rely on online cryptographic protocols, making them resistant to network-based quantum attacks.

Here’s how offline biometric devices work:

• Biometric Capture: The device authenticates users based on their unique biometrics, such as fingerprints. Unlike passwords or PINs, biometric data is inherently secure and not vulnerable to simple guessing or theft.
• Tokenisation: After verifying the user, the device generates a token that represents the user’s identity. This token is time-sensitive and can only be used within a specific timeframe for a single session.
• Offline Operation: The device operates offline, so it is immune to real-time interception by quantum-powered algorithms.
• Back-End Verification: After token generation, the information is transmitted to a secure server where quantum-resistant algorithms ensure the token remains secure even if intercepted.

Advantages of Biometric Authentication in a Post-Quantum World

• Quantum-Resistant Authentication: Biometric data, such as fingerprints, is nearly impossible to duplicate or forge, making it an excellent choice for authentication in the quantum era. The added layer of tokenisation ensures that even if quantum attackers intercept a token, they cannot use it.
• Tokenisation for Added Security: Tokenisation protects sensitive information by isolating it from the data being transmitted, making it harder for attackers to steal or misuse.
• Offline Operation and Reduced Attack Surface: By operating offline, biometric devices lower the risk of cyberattacks, reducing the exposure of sensitive data to quantum threats.
• Layered Security: Combining offline biometric authentication with post-quantum cryptographic algorithms creates a comprehensive and robust security solution.

Ensuring Strong Fingerprint Verification

CardLab and its partner Fingerprints AB stress the importance of selecting reliable biometric sensors for offline verification. Key considerations include:

• Biometric Algorithms: Effective fingerprint sensors should use dense feature sets for precise matching. Minutiae-based algorithms should be augmented with additional mathematical features for better performance.
• Presentation Attack Detection (PAD): Biometric systems should use advanced machine learning techniques to detect fake fingerprints and protect against spoofing attempts.
• Security: Biometric data should be stored in secure elements, and encrypted templates should be used to prevent tampering.

Government and Industry Response to Quantum Threats

Governments around the world, including those in the EU, recognise the risks posed by quantum computing and are investing in research to develop quantum-safe cryptography. Organisations like NIST are leading efforts to standardise post-quantum cryptographic protocols, while industries dealing with sensitive data are already adopting quantum-safe technologies.

In CardLab's view, offline biometric devices offer a practical, immediate solution to protecting critical data as industries transition to quantum-safe technologies.

Steps for Organisations to Take Now

To prepare for quantum threats, organisations should:

• Conduct Quantum Risk Assessments: Evaluate the potential risks that quantum computing poses to sensitive data.
• Implement Offline Biometric Authentication: Integrate offline biometric devices for identity tokenisation into your security framework.
• Adopt Dynamic Passwords: Replace static passwords with offline biometrically generated dynamic passwords to eliminate vulnerabilities.
• Prepare for Post-Quantum Cryptography: Begin migrating to post-quantum algorithms as they become available.
• Adopt a Layered Security Approach: Combine offline biometric authentication with tokenisation and post-quantum cryptography for robust protection.

Future-Proofing Security in the Quantum Era

Quantum computing presents challenges for online security, but by taking proactive steps, organisations can mitigate these risks. Offline biometric devices provide an effective solution against quantum and AI deepfake threats by offering secure offline operations and tokenised identity verification.

As quantum computing advances, it is essential for organisations to adopt quantum-safe technologies to ensure a secure, quantum-era infrastructure. By integrating biometrics, tokenisation, and quantum cryptography, organisations can safeguard their systems in the face of this transformative technology.
