According to the Japan Real Time blog, Toshiba is working on a ‘foolproof' quantum-cryptography system that industry analysts claim cannot be breached.
Using quantum mechanics characteristics provides a means of generating a unique key and (in theory) an infallible eavesdropping breach detection function. If the PRISM spies tried to eavesdrop (assuming they could decrypt security measures even if they did intercept the communication) it would be detected and the session re-established using new keys.
Fundamentally, secure communications and anti-eavesdropping technology is just one layer needed to protect data in transit. Of course, this is valuable but not the 360-degree security that is required to protect data from the vast amount of threats.
The unfortunate truth is that the security world is preoccupied with the idea of stopping breaches – and yet the evidence reveals that clearly is not working. Even in the most well-run and secure estate, most breaches that occur use malware to extract data from systems directly. Ultimately, detecting these types of attack, efficiently and as quickly as possible is where the focus needs to be for Security professionals.
