A group of scientists from Israel have developed a security system based on laser technology which they claim can protect against present and future hackers.

The team from the Tel Aviv University's School of Electrical Engineering said that the existing fibre optic and computer technology can used in the new security system which involves transmitting binary lock-and-key information in the form of light pulses.

The key code is shared by the sender and the receiver and only they can access the data. The lead researcher Dr Jacob Scheuer said if the system is put in place properly then it can provide full proof security today's systems and also future systems.

Dr. Scheuer said that when the researchers designed RSA system for digital information security in the 1070's it was believed that it would provide safety for a long time however it was cracked about 5 years ago. The system has become fragile and thus a new system is required which provides security.

There were concerns that the hackers may access the key being transferred to the receiver, so Dr Sheuer designed a system where the code is sent in binary code in the form of 1s and 0s using light and lasers instead of numbers.

He explained "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."

He has developed his own laser which can reach 3,000 miles without loosing significant part of the data. This technology is more reliable than quantum cryptography technology that relies on quantum properties of photons, he claimed.

He expressed that if the system finds adequate investment it could evolve into a global linkage for international communication.
