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)

Mean fixed broadband download speeds in India have risen by 16.5 per cent during the second quarter (Q2) and third quarter (Q3) of 2019 and topped 34.07 Mbps in September while country-wide Internet speeds were expected to increase, US-based broadband speed tester Ookla said on Wednesday.

“With Reliance Jio’s rollout of its new GigaFiber service in India in early September, we will likely continue to see countrywide speeds increase,” the company said in a statement.

According to the Ookla’s report, which examined the recent trends in Indian telecom market during the last two quarters, India is the leader in mean fixed broadband download speed amongst other neighbouring countries, with Bangladesh at 24.02 Mbps and Pakistan with flat speeds between 8.54 and 9.14 Mbps.

Availability of 4G continues to improve in India as the country’s mobile providers are trying to provide consistent coverage across the country.

This availability is the percentage of an operator’s known locations where a device has access to LTE service (including roaming).

India’s 4G Availability was relatively high at 87.9 per cent across providers during Q2-Q3 2019, which means that Speedtest users had access to LTE service at 87.9 per cent of surveyed locations.

The 4G availability was 58.9 per cent in Pakistan and 58.7 per cent in Bangladesh during the same period.

Ookla looked at fixed and mobile download speeds in the 15 largest cities in India during 2019, Q2-Q3 and found out that Chennai had the fastest mean download speed over fixed broadband (51.07 Mbps), followed by Bengaluru (42.50 Mbps) and Hyderabad (41.68 Mbps).
