One of the biggest challenges of digital technology today is around security systems and data.
While this has proven successful, advancements in quantum computing - which utilises quantum mechanics to solve complex problems faster than conventional computers - could potentially turn data security on its head. IBM, Microsoft and Google have already turned their attention to quantum computing and, as a result, commercially viable quantum computers are not too far from becoming a reality.
Data security needs to be a step ahead, with more advanced cryptographic algorithms that minimise potential risks and ensure the safeguarding of data in a quantum computing world.
Quantum-resistant data security is a concern as current approaches to data protection use algorithms that traditional computing power would take several years to crack.
While quantum computing is widely considered a potential risk for data security, it could potentially also be a part of the solution, as quantum cybersecurity may provide a more robust and compelling opportunity to safeguard critical data.
According to IBM, quantum computing can aid in providing a more robust way to safeguard critical data than current offerings.
In particular, quantum machine learning and quantum random number generation are believed to provide a viable solution to securing data while at the same time wielding the power to detect and deflect quantum-era cyberattacks before they can cause harm.
As encryption is often a key component of data security, adopting quantum-resistant cryptography will be critical to protecting people and adhering to privacy regulations.
As quantum computing is not widely used as yet, it is unlikely that we will be able to harness quantum computing power to develop a quantum-proof approach to data security for a few years.
Thus, before quantum computing becomes widely adopted, most likely as Quantum-Computing-as-a-Service, it is critical to stay a step ahead of the potential threat and develop a quantum-proof solution now, rather than wait for quantum computers to break the current data encryption models.
To prepare for the quantum revolution, companies need to assess their cyber security infrastructure and identify potential vulnerabilities to quantum computing.
Some traditional forms of data security will be made obsolete with the mass rollout of quantum computing it's believed others are capable of withstanding the potential threats of this evolving technology.
Tokenization, which uses randomization to substitute a real value for a token that conceals that value, is believed to be a viable data security option against quantum computing.
This randomization is a powerful data security tool which, unlike key-based encryption that uses mathematical formulae or proofs to ensure the integrity of the algorithm, stores data with random but reversible tokens which cannot be decrypted with a mathematical solution.
Tokenization substitutes the real value with a token consistently across the enterprise which means that data can be joined in a protected state to power AI, ML, data analytics initiatives and other applications that require data from multiple siloes to drive business outcomes.
Already it is believed that threat actors are scraping data, which means they are stealing and holding onto data until quantum computers are more easily available to decrypt it.
Although much is unknown about the impact quantum computing will have, we do know that we cannot wait for it to become commercially available before implementing more stringent security measures to withstand the threat of its computing power.
Investing in data security today is critical to safeguarding data against emerging threats such as those presented by quantum computing.
While quantum computing and data scientists are working to develop solutions that could potentially be quantum-proof, companies stand to benefit from implementing solutions today that are considered secure against threat actors and quantum computing alike as a first step to implementing a multi-layered approach to future-proofing data security.
This is best achieved by partnering with a company, such as Protegrity, which has extensive experience in identifying and classifying sensitive data and safeguarding it with solutions that will stand up against quantum computing to keep data secure today and in the future.
