(TechRadar) Experts are debating how the power of quantum will affect the cybersecurity landscape. Research from the Neustar International Security Council (NISC) recently revealed that almost a quarter of security professionals are already experimenting with quantum computing strategies, worried that it will outpace the development of existing security technologies.
At present, the cybersecurity industry depends on encryption to safeguard devices and personal data. In theory, encryption is possible to crack. In practice, however, it is impossible and would take a colossal amount of time to do so, over timescales of trillions of years.
Encryption’s time as a viable solution is limited. Neustar’s research revealed that nearly three quarters (75%) of cybersecurity professionals expect advances in quantum technology to beat current technologies, such as encryption, within the next five years. Its ability to break encryption techniques such as private key poses a major challenge to the cybersecurity industry. In the wrong hands, it could be used to launch a cyberattack on an unprecedented scale.
There is a crucial need to create new public key schemes that are resistant to quantum technology. Even though a quantum computer capable of beating encryption is approximately ten years away, quantum-proof encryption needs to be implemented before then.
Businesses are also required to take note of all encrypted data and make sure it is surrounded by 24/7 monitoring and threat intelligence tools, alongside robust processes. There needs to be a recognition that even though it is impossible for this data to be decrypted currently, advances in quantum computing will mean that it will be vulnerable in future.
