The world’s first uncrackable security system, which even quantum computers could not hack, has finally been developed by researchers.
Computer scientists had feared that the dawn of quantum computing would allow even the most fiendishly-encrypted data to be easily decoded, causing a major headache for banks, government agencies and communications providers.
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.
I’m perfectly willing to agree that some forms of cryptography, of communication, can be made safe from certain sorts of hacking and decoding. But one from all? Don’t believe it.
We’ve got human beings involved here. There will always be a door somewhere in the system. And anyone who assumes that the system really is uncracked will likely get a rude surprise – Enigma worked out badly precisely ‘cuz the Krauts insisted it couldn’t be broken. Which, with the technologies they knew about, what true.
