Researchers from the Department of Physics at Lancaster University, UK, have patented "an encryption scheme that is so nearly unbreakable that it will be equally unwelcome to internet criminals and official eavesdroppers".
They were modelling how the human heart and lungs pass information between themselves to co-ordinate their rhythmic cycles. They have since filed a patent to implement their complex mathematical model to producing a near-unbreakable encryption method.
The method works by encrypting data using a cipher which makes use of the "coupling functions" between interacting dynamical systems. In the words of the researchers themselves:
"The idea is for the sender to encrypt information at the transmitter as time variations of the coupling functions between a pair of dynamical systems, e.g., electronic oscillators or lasers, analogous to the heart and lungs. At the receiver end, the information is decrypted with another pair of dynamical systems, identical to those in the transmitter and interacting via the same coupling functions, using Bayesian inference."
This method offers an infinite number of encryption keys and allows for several encrypted streams to be transmitted at the same time.
In short: this means the new method is virtually impossible to crack. Let's just hope the research turns into a real-world application.
