Laser security system to fight hackers

Hacking, this is this word which panics many Companies who feel their data is very confidential and which needs to be shared thorugh networks. such as defence networks, governament websites or any other banking websites. But to be frank this work makes think the people who do this are really intelligent. Well Hackers use lot of methods to hack through the network and in some cases they have even cracked the codes which companies felt like they cannot be cracked atleast billion years.

This time scientists have invented a method which can protect the network.Israeli scientists have invented a laser security system which they claim can beat today's hackers and the hackers of the future with existing fibre optic and computer technology.

There are practices being done in developing quantum computers for the future which are very powerful and uses the quantum theory. And these scientists say that even a quantum computer cannot crack the code if they generate the code successfully as per the new laser methods.

The researchers at Tel Aviv University's School of Electrical Engineering have found that by transmitting binary lock-and-key information in the form of light pulses, the device ensures that a shared key code can be unlocked by the sender and receiver and absolutely nobody else.

As i said earlier , hackers are using such a powerful techniques to hack for example When the RSA system for digital information security was introduced in the 1970s, the researchers who invented it predicted that their 200-bit key would take a billion years to crack. "It was cracked five years ago. As computers become increasingly powerful, the idea of using the RSA system becomes more fragile thus the solution lies in a new kind of system to keep prying eyes off secure information.

Imagine the cases where we need to send secure key over a non secure network which is Hacking prone zon, as the hacker once find the key being sent he can grab it very easily.

Dr Sheuer lead of this laser technique found a way to transmit a binary code (the key bearer) in the form of 1s and 0s, but using light and lasers instead of numbers.

"The trick is for those at either end of the fibre optic link to send different laser signals they can distinguish between, but which look identical to an eavesdropper," the author said.

Dr Scheuer developed his system using a special laser he invented, which can reach over 3,000 miles without any serious parts of the signal being lost.

This approach makes it simpler and more reliable than quantum cryptography, a new technology that relies on the quantum properties of photons, the researcher said.

well with this we can already sense the era being started into quantum computers.
