Quantum Computing: Revolutionizing Cybersecurity
The emergence of quantum computing holds transformational power, significantly enhancing speed, efficiency, data transfer, and cybersecurity. This technological phenomenon is expected to deliver data at quantum speed or a million times faster than conventional computers, catapulting our existing digital landscape to new heights.
Quantum computers process data in quantum bits or qubits, simultaneously, through entanglement. By harnessing the laws of physics, the world stands on the brink of achieving the next great digital evolution.
However, its code-breaking possibilities have gained the interest of cyber criminals, leaving enterprises and organizations concerned about possible breaches in encrypted sensitive data.
Quantum-speed cyberattacks can potentially use cryptographically relevant quantum computers (CRQCs) to break public key encryption algorithms. This capability poses a significant threat, as it could disrupt economies and industries reliant on secure data transmission. The emergence of CRQCs highlights the urgent need for new encryption methods to safeguard sensitive information and maintain stability in various sectors.
In a quantum-based communication network, quantum key distribution (QKD) is enabled, where codes on subatomic particles called photons are exchanged, allowing data encryption and decryption. This innovative solution appears to be the most secure solution to date.
However, cybersecurity experts believe that the QKD is only a partial solution and more quantum-resistant innovations should be developed to ensure the digital landscape’s capability to combat the impending quantum threat.
Furthermore, concerns about merging hybrid quantum-classical computing and artificial intelligence (AI) are being raised, indicating the need for more immediate attention, focus, and research.
The massive potential of quantum computers to break traditional encryptions makes crypto agility and interoperability crucial for strategic planning.

The Intensity of Cyber Crimes
As technology becomes more sophisticated, the tactics of cybercriminals are further enhanced as well. The rise of sophisticated cyber threats calls for the adoption of cutting-edge hybrid solutions, integrating the capabilities of AI and machine learning (ML) to detect and respond to threats in real-time.
The existing encryption methods are designed to shield traditional computing systems. However, organizations should be mindful of the risks, particularly when cyber attackers gain full access to the full potential of quantum computing.
While some experts predict Q-Day to arrive in 2030, QUANTUM DEFEN5E (QD5) warns it may come as early as 2025. This urgency stresses the need for global security enhancement to safeguard sensitive data and intellectual property (IP) against theft.
According to Finnish telecommunications giant, Nokia, the global cost of damages resulting from cybercrime is expected to reach USD 10.5 trillion by 2025, signifying the growing urgency for augmented cybersecurity measures across all industries.
Cybercriminals are already advancing their plans by implementing the “harvest now, decrypt later” (HNDL) strategy, where they gather and store encrypted sensitive data for future decryption. This strategy will expose massive volumes of sensitive data, allowing cyber attackers to exploit the vulnerabilities of global organizations when quantum technology becomes available.
With the impending quantum threat, global investors have invested more than USD 2.35 billion in the development of quantum start-ups in 2022 alone, according to a study conducted by McKinsey.
Relying heavily on the secrecy of their data, government institutions are racing to safeguard national interests and secure data against future threats.
Additionally, there are significant risks to the online security of financial institutions, telecommunications, and personal privacy that could be exploited. The potential misuse of advanced quantum computing technology raises concerns about the integrity and confidentiality of sensitive information, prompting the need for enhanced security measures to protect against these emerging threats.
In 2020, Japan’s defense networks experienced a similar dilemma where plans, capabilities, and military assessments were exposed to cyber foes.
In 2023, the sensitive data of Japan’s National Center of Incident Readiness and Strategy for Cybersecurity (NISC) was compromised. The cyberattack raised concerns as it remained undiscovered for almost nine months.
In the same year, the Royal Mail was targeted by ransomware, disrupting international posts in the United Kingdom (UK). The ransomware attack also exposed the personal data of UK police officers.
These incidents highlight the severity of cyber risks, prompting organizations to act swiftly in fortifying their defenses against the evolving technological landscape.

The Quantum-Resistant Cybersecurity Landscape
As the world rapidly embraces digital transformation, amplifying security measures to safeguard the hyper-connected and intelligent ecosystem is more critical than ever. The race to achieve advancements in quantum technology has attracted the public and private sectors alike.
Nokia is at the forefront of developing solutions to combat emerging quantum threats. The entity has integrated advanced cybersecurity protection and quantum-safe encryption into its zero-trust-driven IP and optical technologies to prepare for the advent of Q-Day.
Amazon Web Services (AWS), a leading cloud provider, has implemented an open-source, hybrid post-quantum key exchange, highlighting its efforts to establish PQC. This initiative integrates the Transport Layer Security (TLS) protocol across various AWS services.
Enterprises have also started to develop counteractive measures in response to these emerging threats. For instance, Apple has integrated the quantum-computing resistant PQ3 protocol into iMessage, making the application ultra-secure.
Similarly, another messaging application, Signal, has advanced its protocol to PQXDH, making it quantum resistant. The upgrade offers an additional layer of protection against quantum computing threats.
Moreover, the National Institute of Standards and Technology (NIST) standardized four algorithms related to post-quantum cryptography, establishing a foundational strategy against quantum computing threats. These algorithms include CRYSTALS-Kyber for general encryption and CRYSTALS-Dilithium, FALCON, and SPHINCS+ for digital signatures.
In 2022, IBM unveiled the z16 mainframe, dubbed as the industry’s first quantum-safe system. This technological breakthrough allows the preservation of digital signatures in critical documents through dual-signing structures using NIST’s cryptographic algorithm, CRYSTALS-Dilithium.
Global standardization bodies, such as 3GPP and the Internet Engineering Task Force (IETF), have begun incorporating post-quantum cryptography (PQC) into security protocols of future standard releases.
In addition, the United States (U.S.) and China lead in the race for quantum technology investments. In 2023, the U.S. invested USD 1.8 billion while China spent more than 15.3 billion to execute their quantum computing efforts. These two countries are at the forefront of harnessing the power of quantum technology to accelerate economic growth and safeguard digital assets and cyber records for national security.
In the Middle East, the Technology Innovation Institute in Abu Dhabi developed cryptography estimators in 2023, assessing PQC security. Recently, the UAE’s Cybersecurity Council also launched new policies to be implemented by the end of 2024. The strategic move includes the implementation of an "encryption law," designed to establish standards for data transmission security that are compatible with quantum computing systems.
