Why encrypt your data?

Encryption is used to ensure the confidentiality, integrity, authentication and non-repudiation of data, both at rest and in motion. In layman’s terms, it ensures that your data remains secret, that nobody has tampered with it, that it was sent to the right person in the right order and that you can prove who sent it.

In the past it was often incorrectly assumed that data was somehow protected when sent along dedicated (private) optical fiber networks, as the assumption was that these could not be tapped. Or that MPLS networks would protect data through virtual segmentation of the different users. Such assumptions have been proven false time and again.

Encryption represents the best line of defense against data breaches – ensuring that the data itself is rendered useless if it falls into unauthorized hands. In fact, encryption is increasingly mandated by new data protection rules. However, not all encryption solutions are created equal.

The value of quantum cryptography

With the age of quantum computing drawing ever-closer, traditional encryption methods are at risk. While brute force attacks can take months to break through security, quantum attacks can use more advanced techniques to break standard public key cryptography in a much shorter timeframe.

Even if quantum computers only appear in the next decade, as is widely held to be the case, today’s public key cryptography is still not proven to be secure against mathematical attacks. Moreover, the threat posed by future quantum computers still affects data today – the “download now, decrypt later” attack vector means that (encrypted) sensitive data can be downloaded today & analyzed offline when a quantum computer appears.

The only solution to provide provable forward secrecy of critical data is to implement quantum-safe encryption today. Using quantum cryptography now will provide immediate protection to your data in the face of today’s brute force attacks, ensure that data with a long shelf life is protected against future attacks and safeguard high-value data in a post-quantum computing world.
