While many companies are still discussing quantum resistance, the Bundeswehr's 13.000 kilometer long fiber optic network is quantum-resistant encrypted. The cryptography solution is approved by the BSI up to “VS-NfD” and enables bandwidths of up to 100 Gbit/s. Over the past three years, the BWI has completely modernized the Bundeswehr’s wide area network. The new core network, the so-called backbone, of the nationwide fiber optic network is not only significantly more powerful. It is also quantum-resistant encrypted and approved by the BSI up to “VS-NfD”. VS-NfD: Classified information – only for official use The entire voice and data communication of the Bundeswehr in this country is carried out via...

BSI study on the development status of quantum computers

26 November 2023

The Federal Office for Information Security (BSI) has published the update of the “Development status of quantum computers” study. The ongoing development threatens many cryptographic methods currently in use. When planning the necessary transition to quantum-secure cryptography, a reliable assessment of the risk posed by quantum computing to information security is essential. The study presents the development status of current technologies for realizing a cryptographically relevant quantum computer as well as cryptographically relevant quantum algorithms. Quantum computers could crack passwords The advancing development of quantum technologies threatens many cryptographic methods currently in use. Data that is currently not transmitted in quantum-secure encrypted form and…

Highest encryption cracked with quantum computers?

15 November 2023

The currently highest encryption is the RSA-2048 key. The researcher Ed Gerck Ph.D, physicist and mathematician, now claims to have cracked this using a quantum computer. If all of this were true, all companies would have to put the topic of post-quantum cryptography – i.e. quantum-secure encryption – at the top of their to-do list. The news that researcher Ed Gerck claims to have cracked the RSA-2048 key is currently stirring up a lot of dust. He also claims to have achieved this with a commercial mobile phone or Linux desktop. Ultimately, this would mean that many encryptions for access and passwords in the future will be anything but secure...

Post-Quantum Cryptography

3 April 2023

IT security specialist Cloudflare announces the standard and free deployment of post-quantum cryptography to protect its websites, APIs, cloud tools and remote workers from future threats. This now allows all Cloudflare customers to smoothly enter the next era of cybersecurity standards—instantly and at no cost. Setting the course before things get serious Quantum computers solve complex arithmetic tasks many times faster than today's computers and are expected to reach such a sophisticated level in the next few years that they will be able to decrypt most of the encrypted data on the Internet. Recently, the administration of the US President...

Post-quantum cryptography for websites and APIs

5 November 2022

Cloudflare has introduced support for post-quantum cryptography for all websites and APIs served over Cloudflare's network. With this, Cloudflare enables the support of post-quantum cryptography on almost 20% of the Internet. The use of quantum computers is steadily increasing. In the future, quantum computers will be able to decrypt encrypted communication. The problem: cryptography for every type of application (no matter how commonplace) has an expiration date: from email and online banking to medical records and government secrets. Thus, quantum computers potentially pose a major security challenge for companies, individuals and governments….

Post-quantum cryptography: encryption against quantum computers

13 October 2022

Algorithms used today for encryption may soon prove too weak - once quantum computers become practical. Algorithms and hardware must therefore be developed that can also withstand these powerful supercomputers: post-quantum cryptography. A few years ago, the US federal agency National Institute of Standards and Technology (NIST) initiated a process to define/evaluate quantum-resistant algorithms. The potential candidates were selected in various rounds. In total, more than 80 algorithms were proposed, some of which were dropped quite early. The reason for this was that mathematical attacks were developed for quantum computers that break the algorithms...

Can quantum computers crack all cryptography?

7 November 2021

Quantum computers are able to completely and irreversibly break the most widely used public key procedures today. Post-quantum cryptography can prevent this. But how safe are the new procedures and what should be considered when implementing them? What sounded like science fiction a few years ago is now within reach: quantum computers with a previously unknown computing power endangering today's cryptography - and thus the entire digital infrastructure. Quantum computers: the danger that comes from the future Although it will probably take a few years before it can be used across the board, it still applies ...
