Description

Secure encryption is an inescapable feature of modern life. It affects aspects of mobile communication, sensor networks, bank transactions, the Internet, car-keys and so on.  

In each case we must be able to pass information privately such that only the intended recipient can decrypt and understand it. Unfortunately, rapid progress in illicit decryption brings a continuing need for new encryption schemes that are harder and harder to break. Here we offer a novel encryption scheme derived from biology, radically different from any earlier procedure. Inspired by the time-varying nature of the cardio-respiratory coupling recently discovered in humans, we propose a new encryption scheme that is highly resistant to conventional methods of attack.

Our new scheme encrypts information signals as the time-variations of linearly-independent coupling functions between interacting dynamical systems (analogous to the heart and lungs). Using the predetermined coupling functions, we can apply Bayesian inference on the receiver side to decrypt the information signal. The use of coupling functions in this way confers an unbounded number of encryption key possibilities. We demonstrate that it enables more than one signal to be transmitted/received simultaneously and that it is exceptionally robust against external noise.

The new encryption scheme is quite general, so that it will be applicable to many different communications technologies.   It allows great freedom in the encryption process without changing the qualitative state of the system, is highly modular, and is readily extendable to support a diversity of different applications within the same conceptual framework.
