The Forbes Technology Council posits that as much as quantum computing has a long list of benefits, it also has a share of risks. Quantum computing, a multidisciplinary field that utilises quantum mechanics to solve complex problems, can expose users to various security threats.
“Data securely protected today could be lost to a bad actor that gains access to a future cryptographically relevant quantum computer. These threats will apply to all data, systems, and technologies that are not made quantum-safe,” says Catherine Lian, IBM ASEAN’s GM and Technology leader.
Urgency of quantum-safety
Through projected misuse of a cryptographically relevant quantum computer, harvested, stolen, or lost confidential data over the years could be decrypted. Malicious players can take advantage of digital signatures, legacy systems, digital evidence, and assets on long-term blockchains.
All data, systems, and technologies not made quantum-safe by transitioning to post-quantum cryptography continue to face these risks.
However, cybersecurity infrastructure takes a long time to upgrade. There is urgency in replacing cryptography with quantum-safe cryptographic schemes to mitigate projected risks.
“We believe that the time to start is now. Enterprises need to begin to understand the risks of quantum computing, particularly with respect to quantum-safe, and begin creating an inventory of cryptography usage across the enterprise so they have a comprehensive view. And if planned and executed properly, this can be done in a structured and incremental manner,” Ray Harishankar, IBM Fellow, IBM Quantum-Safe, says.
