The Quantum Computing Threat to VPNs

Google, IBM, and other tech companies are developing quantum computers which are more powerful than conventional computers. They work by storing information in a quantum form - a form based on atomic level particles. Rather than storing data in bits, data is stored in qubits in a quantum form.


Cybersecurity professionals are already developing virtual private networks which have encryption that can protect data from hacking attempts performed with quantum computers. As discussed in the Tip of the Night for September 30, 2019 VPNs send data through a provider's server and encrypt it. An quantum computer would have enough power to run calculations necessary to crack current cryptography keys.


The National Institute of Standards and Technology (NIST) has initiated a program to develop encryption strong enough to provide protection for when quantum computers are widely used.
