Hiinlased täitsid lubaduse: Hiina riigi, lahtihäkkimatu, satelliitside tegi oma esimese sideseansi. |
|
|
Meenutuseks - eelmisel aastal - lubasid hiinlased, et nad ehitavad sellise satelliitside mida ei suuda keegi lahti häkkida või lahti murda.
Nüüd on siis hiinlastel selline satelliitside testimiseks olemas ja tehti esimene infovahetus selle uudse lahendusega.
Chinese Quantum Satellite Sends First "Unhackable" Data to Earth
In August last year, China launched the world's first quantum communication satellite into the Earth’s orbit aboard a Long March-2D rocket to test the fundamental laws of quantum mechanics at space.
Dubbed Quantum Science Satellite, nicknamed Micius or Mozi (Chinese: 墨子), the satellite was designed to establish a 'Hack-Proof' communications system in this age of global surveillance by transmitting unbreakable encryption keys from space to the ground.
Now, it has been reported that using this satellite, the Chinese scientists at the Quantum Experiments at Space Scale (QUESS) project were able to send secret "quantum key distribution" (QKD) data by beaming photons from the space to the ground stations over longer distances than ever before.
The Chinese scientists successfully sent quantum keys over a distance of 1,200 Km (745 miles) from space to Earth at a transmission rate up to 20 of magnitudes more efficient than that expected using an optical fibre of the same length, lead scientist Pan Jianwei told the official Xinhua news agency.
"That, for instance, can meet the demand of making an absolute safe phone call or transmitting a large amount of bank data," Jianwei said.
The Quantum Science Satellite could become the world's first transcontinental quantum key distribution network of its kind and China hopes to erect a global quantum cryptography-based communications network in 2030.

Üks näide kah kuidas võiks käia "Küber-GPS sõda" ja kuidas siis hiinlaste lahenduse korral oleks siis taoline "sõda" mõttetu kuna keegi ei saa infot muuta endale vajalikus suunas.

Ships fooled in GPS spoofing attack suggest Russian cyberweapon
Reports of satellite navigation problems in the Black Sea suggest that Russia may be testing a new system for spoofing GPS, New Scientist has learned. This could be the first hint of a new form of electronic warfare available to everyone from rogue nation states to petty criminals.
On 22 June, the US Maritime Administration filed a seemingly bland incident report. The master of a ship off the Russian port of Novorossiysk had discovered his GPS put him in the wrong spot – more than 32 kilometres inland, at Gelendzhik Airport.
After checking the navigation equipment was working properly, the captain contacted other nearby ships. Their AIS traces – signals from the automatic identification system used to track vessels – placed them all at the same airport. At least 20 ships were affected.
