Bundle1 Un hackable telecommunications networks soon to be the norm

Researchers with Toshiba’s European research laboratory are saying they have a way of protecting telecoms networks using special quantum cryptography.

In a recent paper titled, “Coexistence of High-Bit-Rate Quantum Key Distribution and Data on Optical Fiber”, researchers say they can protect these networks without the need of dedicated fiber optic links.  The synopsis of the paper reads in part:

In the world of traditional communications, it is impossible for one person who receives a set of encryption keys from another to know whether or not the keys have been seen by the eyes of an eavesdropper. However, quantum key distribution (QKD), which encodes keys in the quantum states of a medium, can achieve the impossible by exploiting the fundamental quantum property that any eavesdropping on a quantum state always leaves a trace.

Telecoms networks are often prey to malicious hackers trying to cause mischief or even harm to Internet data.  Using new advances in quantum cryptography, the researchers have come up with new code encryption that is theoretically un-crackable by malicious hackers.  Furthermore the new encryption supposedly lets one know if someone was trying to decipher it.

The encryption research was done by Cambridge University in conjunction with Toshiba European research laboratory.  They claim this research will eventually be protecting all manner of data ranging from private company data, personal identity and credit card information.

It is said that many military agencies and governments may already be using a very similar type of encryption technology.  However,  the information taken from the research states that the quantum keys are being sent on separate lines carrying the information to be decoded or encoded.

The research on the new encryption techniques can be found in the scientific journal, Physical Review X.
