Security: A New Algorithm Provides ‘Unbreakable’ Encryption
Encryption algorithms are often based on ‘keys’. Algorithms to date have been based off of selecting a key from a very large, but still finite, set. If someone had enough time and computing resources, codes can be eventually hacked. But now researchers have come up with a way that enables generation of an infinite set of possible keys. And that’s a big step forward in encryption security. The new method has also been found to be exceptionally resistant to interference from the random fluctuations or “noise”, which would make it a good choice for use in mobile and remote sensing devices.
Peter McClintock, professor at Lancaster University Physics department, said that “this promises an encryption scheme that is so nearly unbreakable that it will be equally unwelcome to internet criminals and official eavesdroppers. 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 functions recently discovered in humans, we propose a new encryption scheme that is highly resistant to conventional methods of attack.”
Aneta Stefanovska, professor at Lancaster University Physics department, said that “knowing about some of the open problems in encryption, we suddenly realized that what we tried to understand in biology can also be applied here. ‘Coupling’ essentially involves a time-varying delay, that when translated to encryption systems means an infinite number of secret encryption keys shared by the sender and recipient is possible. It means it is ‘highly resistant to conventional methods of attack’.
