As cyberattacks grow in number and sophistication, it is essential that data is protected. But in today’s evolving threat landscape, this is not as simple as applying traditional security to communications systems. Indeed, many current systems use protocols based on mathematical problems, such as integer factorization, which could be easily cracked by quantum computers of the future.

This is a major concern that could have a devastating impact because it encourages cybercriminals to harvest data traffic with the hope of decrypting the information when the technology becomes available to do so. This becomes an even more serious threat at a time when data confidentiality must be maintained for several years as mandated by data protection regulation – especially as it is now feasible to store large volumes of information.
