Engineers have shew a new communication system designed to protect telecommunications against quantum computing attacks .
The system , called " QS7001 , " was submit on Jan. 22 by illustration of the Swiss semiconducting material company SEALSQ at theWorld Economic Forumin Davos , Switzerland .
The QS7001 system combines two quantum-resistant encryption protocols to reduce the window of opportunity for attackers.
To protect data transmitted over the internet , from defrayment information to personal medical records , the contents of substance are inscribe .
encoding scrambles information using mathematical problem so complex that they can not be solve without a " key , " which only the authorised parties ( the transmitter and receiver ) have access to . Although encryption does not in itself forbid interception of the message , it prevent anyone from interpret the content .
However , scientist theorize that the massive processing power of futurequantum computerswould admit them to solve complex equations in moment , where classical computers would have taken gazillion of years . They therefore have the potential to break conventional encoding applied science , such asRSA encryption .

A feeble 50 - bit whole number of RSA ( NISTrecommends a lower limit of 2048 - bit ) encoding has already beenbroken using quantum computers . globose communication could be disrupted if the great unwashed could no longer securely beam messages over the cyberspace gratuitous from the threat of interception .
The QS7001 system combines two quantum - resistant encoding protocols develop by NIST ( DilithiumandKyber ) with a step-down in data point transmitting time — thereby exit the possible window of chance for attacks .
" It ’s the organic evolution of the ever - present munition race between technology to keep us safe and technology that can be used to undo it , " Dave Lear , a cybersecurity analyst , told Live Science .
Narrowing the window of opportunity
Quantum - repellent protocols are new encoding technique that have test resistant to quantum calculation attacks — in that quantum computers are unable to solve the cryptographic paint to the encryption and get at the data . However , quantum computers are becoming more and more powerful and could , in the hereafter , even break encoding that is currently tolerant to quantum attack .
" The producer are lay claim it ’s quantum - tolerant , but until it ’s properly test in the state of nature — and attacked by determined resister — we wo n’t have a go at it for sure , " pronounce Lear .
In the presentment , it take a traditional dependable microcontroller up to 1,500 milliseconds ( one and a one-half seconds ) to transmit sampling data protected using the Dilithium encryption communications protocol . Using the SEALSQ ’s QS7001 method acting , it took approximately 100 ms ( one - ten percent of a second ) to transmit the same data .
This reduced transmission system time was accomplish by expeditiously authenticating , signing and encipher information while still adhering to the same stringent certificate certifications . This proficiency reduced the time that a quantum computer had to intercept and break the encryption of messages .

It is worth noting that this method does not foreclose intercepted data from being copied and stored — and at that point , a quantum computer would not be tighten by the abbreviate transmission sentence . However , what the QS7001 does is narrow the window of chance for interception and foreclose intercepted messages from being change or misdirected .
There are also emerging quantum communication technology that can be used to detect if a subject matter is being tap and call off the infection . If QS7001 were to be conflate with quantum communication theory , this could become a knock-down tool for protecting our entropy on a post - quantum net .
" If it shoot longer to decrypt than that paint is valid for , then your content is protected , " suppose Lear . " Until they develop a riotous tool , of course . "
