22 July 2024 - Emerging technologies are on the watch list in the cybersecurity space. While the current focus falls on the potential threats technology like AI and IoT pose to cybersecurity protocols, one to watch for the future is Quantum computing. This powerful technology has the potential to overpower current cybersecurity measures but also holds the key to enabling much more robust levels of security and privacy in the future. By understanding the basics of quantum computing and how it relates to the future of cybersecurity, you can understand the potential risks, take preventative steps for information security, and see this powerful advancement as an exciting possibility rather than something to fear.
The vulnerabilities of current encryption methods
Traditional computers currently in mainstream use, rely on cryptographic algorithms for the protection of sensitive information and secure communications. Quantum computing makes it possible for these algorithms to be decrypted quickly, putting the confidentiality of data at risk.
Public-key cryptography is a technology in widespread use that is under threat. One of its main functions is securing online communication and transactions. Foundational algorithms and key exchanges that secure online activities are at risk of being compromised by quantum computers, potentially exposing vast amounts of sensitive information.
What is quantum computing?
Quantum computing is a technological innovation that offers unprecedented computing power. It does this by applying the principles of quantum mechanics. Unlike traditional computers that rely on bits represented as 0 or 1, quantum computers operate using quantum bits or qubits, which can exist in multiple states at the same time. This allows quantum computers to perform calculations in parallel, making them much faster than traditional computers.
Quantum computing risks for cybersecurity
The impact of quantum computing on cybersecurity is substantial. While this incredible technology has the potential to improve and significantly change many technologies including data analysis and optimisation, it also holds significant challenges for traditional cybersecurity measures. The strength of quantum computers lies in their capability to solve complex problems exponentially faster than traditional computers, leading to concerns about their potential to break conventional encryption methods and compromise data security.
Understanding the intersection of quantum computing and cybersecurity is crucial for developing robust defence mechanisms in the face of evolving cyber threats. As quantum technology continues to advance, the need to adapt encryption strategies, enhance data protection protocols, and prepare for quantum-enabled cyber risks becomes increasingly pressing in safeguarding sensitive information and preserving digital privacy.
Enhancing Data Security with Quantum Technology
On the positive side, quantum technology can also help vastly improve existing cybersecurity methods. Quantum computers can be used in developing new forms of encryption like Quantum Key Distribution (QKD), which is considered virtually unhackable. QKD uses quantum cryptography to ensure secure communication, providing a significant advantage over traditional methods.
As quantum technology develops, researchers are making assumptions on how it could benefit cyber security. It is expected to play a vital role in the early detection of cyberattacks before any significant damage is done. Likely, it will also be used to develop more robust cryptography standards to provide stronger protections for digital data.
Post-quantum cryptography (PQC) is a more advanced cryptographic algorithm, the development of which requires quantum calculations. At the moment, algorithms cannot generate truly random encryption numbers as the code they are built on follows a pattern. Quantum algorithms are expected to act as truly random number generators and offer pure randomisation, providing the highest possible standard of data security. They will be virtually impenetrable because guessing the random number correctly is patternless.
Future of Cybersecurity with Quantum Computing
When it comes to cyber security, quantum computing has the potential to enable a much more robust level of communication security and privacy. Although the real impact of large-scale quantum computers is about a decade away, the technology available now can still offer great benefits. As with all new technologies, come new opportunities for cybercrime. To put your mind at ease, know that major tech companies are continuously building new protections to withstand quantum cyber attacks and organisations like The World Economic Forum have designed a governance and principles framework for quantum computers to ensure they are used as responsibly as possible.
As a preventative measure, businesses and organisations should be aware of the long-term risks and put plans in place for the future quantum revolution and all the changes it will certainly bring.
