Randomness is at the heart of any cyber security system, and although randomness is often assumed to be straightforward to achieve, in reality it is fraught with complexity.
To take security to where it needs to be in this technologically advanced age, every computing device from computers to smartphones; from medical implants to autonomous cars, needs access to high-quality random numbers to be secure. The quality of a random number generator refers to how difficult it would be to predict its output. The more random, the more secure.
This need is fuelling a rise in random number generators underpinned by quantum technologies. However, recent research has shown quantum random number generators are not providing the promised true randomness, moreover the generation rate is also slower than expected. This creates a major opportunity for a new product in the market which has a high quality of randomness, plus a high rate of generation.
BioGenerate - for when quantum is not random enough.
At BioGenerate, we have developed a solution which harnesses the true randomness of the body’s biological signals to extract extremely high-quality random numbers, very efficiently. Without the need for expensive quantum technology, the BioGenerate product is much more affordable and yet delivers superior randomness at a faster rate.
Our solution adds particular value to the encryption of device to device communications, for example addressing the security challenges inherent in keyless entry or more critically, the communications between medical implants and their external control devices.
BioGenerate, is a collaboration between Imperial College, London and the University of Gloucestershire.
