New quantum random number generator could revolutionize encryption


Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption developed at Linköping University.

The researchers behind the study believe that the new technology paves the way for a new type of quantum communication.

Safeguarding data made simple with encryption

The most common way to protect information is through encryption. So when we send emails, pay bills and shop online, the information is digitally encrypted.

To encrypt information, a random number generator is used, which can either be a computer programme or the hardware itself. The random number generator provides keys that are used to both encrypt and unlock the information at the receiving end.
