Quantum Computers Threaten to Destroy Internet Security As We Know It
The expectation is that quantum computers will be built some time after 2025. Such computers make use of quantum-mechanical properties and can therefore solve some particular problems much faster than our current computers. This will be useful for calculating models for weather forecasts or developing new medicine. However, these operations also affect protection of data using RSA and ECC. With today’s technologies these systems will not be broken in a hundred years but a quantum computer will break these within days if not hours.
TU/e professor of Cryptology Tanja Lange.
Without protection a lot of sensitive information will be out in the open, even data from years back. “An attacker can record our secure communication today and break it with a quantum computer years later. All of today’s secrets will be lost,” warns Tanja Lange, professor of Cryptology at Eindhoven University of Technology. This concerns private data, bank and health records, but also state secrets. Lange saw the importance of alternative systems already back in 2006 and is busy with creating awareness and developing new systems. “Fairly recently we’re seeing an uptake of post-quantum cryptography in the security agencies, e.g., the NSA, and companies start demanding solutions.”
Research consortium
Lange leads the research consortium PQCRYPTO consisting of eleven universities and companies. PQCRYPTO started in 2015 with 3.9 million euro funding from the European Commission to develop new cryptographic techniques. “This might seem like a lot of money, but is a factor of 100 less than what goes into building quantum computers.” says Lange. She cautions that it is important to strengthen research in cryptography. “Bringing cryptographic techniques to the end user takes often another 15 to 20 years, after development and standardization.”
Shor’s algorithm
In their Nature publication Lange and Bernstein explain that a certain quantum algorithm, namely Shor’s algorithm, breaks all cryptographic techniques that are currently used to establish secure connections on the Internet. Candidates for post-quantum cryptography can roughly be categorized into two types: they are either very well understood and confidence-inspiring but require a lot of bandwidth or they are more convenient to use but provide more questionable security.
Nature
The publication appears in an issue of Nature with special attention to topics related to quantum computers: from different candidates of elementary building blocks of quantum computers till, e.g., the development of new algorithms. The journal invited Lange to write the article on post-quantum cryptography.

jdp…they should get the quantum cpu to design the needed computer security from firewalls to routers, multi source and single source systems. bio hex metric, and algorithmic routines that can distinguish between real and altered data, per haps instead of a binary system using a trinity system this is a 3 bit system where one bit is a control bit so it knows what is to follow and when that is un true it does a soft reset, of that function and id’s where the alt data came from by time, position, word, IP, TO INCLUDE THE SOURCE VIA PING PONG SYSTEM.SO IT WOULD BE VERY HARD TO FOOL A NANO QUANTUM SYSTEM. A QUANTUM SYSTEM MAY NEED FOUR OR MORE SOURCES TO BE VERIFY USERS A BIO SOURCE, A PIN SOURCE, A PHRASE SOURCE, AN ENCRYPTED SOURCE. AND SOME OF THESE COULD BE AUTOMATED. SO NO BODY KNOWS. AUTOMATE THE PIN AND ENCRYPTION EACH TIME LOGGING IN. TAKE THE FINGER PRINT MERGE WITH FACE RECOGNITION DIGITIZE, ENCRYPT FOR PROTECTION, THE PIN IS A RANDOM NUMBER GENERATED BY THE SYSTEM. ID THEFT had been to easy due to very simple non duplex inputs, encryption could be changed from 4 of 8 code to many of many code randomly, thus trying to figure out what code or pin would me most impossible.
