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)

Parental Control Apps May Not Help in Shielding Teenagers From Cyber Threats

Teenagers may not be safe from cyber threats despite of the parental control apps

Mobile apps designed to help parents keep their teenaged children safe from online predators may harm the trust between a parent and child, as well as reduce the child’s ability to respond to cyber threats, to researchers say.

The findings showed that the use of parental control apps was associated with teenagers experiencing more, not fewer, online risks, including unwanted explicit content, harassment, and online sexual solicitations.

“Parental involvement and direct supervision were both associated with fewer peer problems and less online victimisation for teenagers, but neither of these factors correlated with the use of parental control apps,” said Arup Kumar Ghosh, a doctoral student in the University of Central Florida.

“Our findings suggest that most parental-control apps are those that attempt to control what teenagers can do online, but ultimately do little to keep them safe online,” added Pamela Wisniewski, Assistant Professor at the University.

In another study, the team analysed 736 publicly posted reviews written by teenagers and younger children for parental-control apps available for download on Google Play.

They found that approximately 79 per cent of the reviews written by children rated the apps at either two stars or less out of a possible five.

It is because the apps were overly restrictive, were an invasion of their personal privacy, and supported “lazy” or bad parenting instead of improving communication channels between them and their parents.

The apps also prevented them from doing everyday tasks, such as homework assignments, and turned their parents into “stalkers.”

“Teenagers and even younger children told us loudly and clearly that they would rather their parents talk to them than use parental control apps,” Ghosh said.

By trying to completely shield teens from experiencing any and all online risks, some parents are keeping teens from developing the necessary coping mechanisms that they will need throughout their lives, the researchers suggested.

The results will be presented at the Association for Computing Machinery’s Conference on Human Factors in Computing Systems in Montreal.
