What is Quantum Computing? 

The term “quantum” refers to quantum computing, which is a field that explores the principles of quantum mechanics to develop a new paradigm of computing. 

Quantum computing involves using quantum bits, or qubits, as the fundamental units of information. Unlike classical computers that use classical bits (0s and 1s), qubits can exist in a superposition of states, representing both 0 and 1 simultaneously. This superposition allows quantum computers to perform computations on multiple possibilities in parallel, potentially offering significant computational advantages for certain problems. 

By programming the initial conditions of the qubit, quantum computing can solve a problem when the superposition state collapses. The forefront of quantum computer research is in linking greater numbers of qubits together to be able to solve larger and more complex problems. 

What is computing?

Computing refers to the process of using computers or computational systems to perform tasks and solve problems. It involves manipulating and processing data, executing instructions, and generating results or outcomes. Computing encompasses a wide range of activities, from basic arithmetic calculations to complex simulations, data analysis, artificial intelligence, and much more. 

Examples of Quantum applications  

• MRI scanners for medical imaging 
• Lasers 
• Solar cells 
• Electron microscopes 
• Atomic clocks used for GPS 

Quantum Computing and Cybersecurity Threats 

Quantum computing will enable great innovations in the future, but it will be accompanied by diverse risks. 

What are the key cybersecurity threats at play? 

• Threat 1: Harvest Now, Decrypt Later 
• Threat 2: Making Asymmetric Cryptography Obsolete 
• Threat 3: The vulnerabilities of blockchain technology 

• Threat 1: Harvest Now, Decrypt Later 

Quantum computers have the ability to break many of the widely used encryption algorithms that currently protect sensitive information. The “Harvest Now, Decrypt Later” threat suggests that hackers could collect encrypted data now and store it for decryption in the future, once quantum computers with sufficient computational power become available. This means that data encrypted today, which may seem secure against classical computers, could potentially be decrypted in the future using powerful quantum computing algorithms. 

• Threat 2: Making Asymmetric Cryptography Obsolete 

Asymmetric cryptography (also known as public-key cryptography) is a fundamental building block of modern cybersecurity. It relies on the use of two mathematically related keys: a public key for encryption and a private key for decryption. The threat of quantum computing is that it could render asymmetric cryptography obsolete by breaking the underlying mathematical problems that provide its security. Once large-scale quantum computers become a reality, they could effectively factor large numbers or solve the discrete logarithm problem, making current asymmetric encryption methods vulnerable to attacks. 

•   Threat 3: The vulnerabilities of blockchain technology 

Blockchain technology, known for its decentralized and tamper-resistant nature, underpins various cryptocurrencies and other applications. However, quantum computing could introduce vulnerabilities to the security of blockchain technology. For example, the use of quantum computers could compromise the cryptographic algorithms and digital signatures used in blockchains, potentially leading to unauthorized access, data manipulation, or theft of digital assets. As a result, the integrity and security of blockchain-based systems could be at risk in a post-quantum computing era. 

What is the role of Quantum Computing in Cybersecurity?

These algorithms are designed to be resistant to attacks from both classical and quantum computers, ensuring secure communication even in the presence of powerful quantum adversaries. 

• Quantum Key Distribution (QKD): Quantum computing can also contribute to cybersecurity through quantum key distribution. QKD leverages the principles of quantum mechanics to enable the secure distribution of encryption keys. The inherent properties of quantum systems make it possible to detect any eavesdropping attempts, ensuring the confidentiality of the keys. 

• Random Number Generation: Quantum randomness can improve the generation of truly random numbers, which are crucial for cryptographic applications. Quantum random number generators (QRNGs) produce unpredictable and unbiased random numbers that are essential for secure key generation, seed generation, and other cryptographic protocols. 

• Attacks and Defenses: While quantum computing poses challenges to classical cryptographic systems, it can also facilitate new attack vectors. Quantum algorithms like Grover’s algorithm can speed up the brute-forcing of symmetric encryption keys. Therefore, it is crucial for cybersecurity professionals to develop quantum-resistant algorithms and defenses to safeguard against these potential threats. 

• Quantum-Safe Solutions: Organizations and governments are actively researching and developing quantum-safe solutions to protect sensitive data and critical infrastructure from quantum attacks. These include exploring lattice-based cryptography, code-based cryptography, multivariate cryptography, and other post-quantum cryptographic algorithms that are resistant to quantum computing attacks.
