Circa 2019
Makers of Titanic claimed that it is ‘unsinkable’ and we know how it went down in history. Now, researchers from the University of St Andrews have claimed to have developed an ‘unhackable’ encryption system that stores data in the form of light.
The chip designed by the researchers generates one-time-only key when data is sent through it. The data is stored as light and passed through a specially designed chip that bends and refracts the light to scramble the information.
The trick behind the tech is that the bending and refracting of light is unique every time as it depends upon the data being sent through the chip. It would be safe to say that the chip is a physical realization of the OTP mechanism which is popularly used today to authenticate several services.
