English to Chinese Tech/Engineering IT (Information Technology) security

As far back as 1917, scientists had proposed that ‘perfect secrecy’ could be achieved if it was possible to change the key which encrypts a message each time, based on the message itself.

Now, the University of St Andrews and international partners, have done just that, creating a type of chip which effectively creates a one-time-only key from the data being sent, {scrunching it all up} before sending, in a way that could never be hacked.
