New York, Nov 27: In a bid to fight against the future cyber threats, scientists have developed a new system with high-speed encryption properties that drives quantum computers to create theoretically hack-proof forms of data encryption.

The novel system is capable of creating and distributing encryption codes at megabit-per-second rates, which is five to 10 times faster than existing methods and on par with current internet speeds when running several systems in parallel.

The technique is secure from common attacks, even in the face of equipment flaws that could open up leaks.

“We are now likely to have a functioning quantum computer that might be able to start breaking the existing cryptographic codes in the near future,” said Daniel Gauthier, Professor at The Ohio State University.

“We really need to be thinking hard now of different techniques that we could use for trying to secure the internet,” Gauthier added, in the paper appearing in the journal Science Advances.

For the new system to work, both the hacker as well as the sender must have access to the same key, and it must be kept secret.

The novel system uses a weakened laser to encode information or transmit keys on individual photons of light, but also packs more information onto each photon, making the technique faster.

By adjusting the time at which the photon is released, and a property of the photon called the phase, the new system can encode two bits of information per photon instead of one.

This trick, paired with high-speed detectors powers the system to transmit keys five to 10 times faster than other methods.

“It was changing these additional properties of the photon that allowed us to almost double the secure key rate that we were able to obtain if we hadn’t done that,” Gauthier said. (IANS)

WhatsApp Messages Can be Traced Without Diluting end-to-end Encryption

WhatsApp has maintained that allowing traceability will dilute its end-to-end encryption which ensures that only the sender of the message and the recipient can see the message – not even WhatsApp itself

With India pressing for traceability of WhatsApp messages to check the spread of fake news, a professor at the Indian Institute of Technology-Madras on Wednesday stressed that the issue can be easily resolved without diluting end-to-end encryption and affecting the privacy of users.

“If WhatsApp says it is not technically possible to show the originator of the message, I can show that it is possible,” said V. Kamakoti, while delivering a lecture at Indian Council of World Affairs here.

“When a message is sent from WhatsApp, the identity of the originator can also be revealed along with the message. So the message and the identity of the creator can be seen only by the recipient. When that recipient forwards the message, his/her identity can be revealed to the next recipient,” he said, adding that as per court ruling, those who forward a harmful message can also be held responsible in certain cases.

“In this way, you do not need to break end-to-end encryption and infringe the privacy of anyone and yet make the messages traceable when the investigating agencies want to find out. And this is what we have projected to WhatsApp,” he said.

India started pressing for traceability of WhatsApp messages after several lynching cases last year were linked to rumours spread on the messaging service.
