The EU has drawn up a roadmap for quantum-secure encryption by 2030. By then at the latest, all encryption methods should have been converted in such a way that even quantum computers will be able to cope. <\/p>\n\n

According to current estimates by Europol, current procedures will remain secure for around 10-15 years(https:\/\/www.heise.de\/news\/Europol-Finanzinstitute-sollten-rasch-auf-quantensichere-Kryptografie-umsatteln-10274967.html)<\/a>– provided that the development of quantum computers and procedures continues at the current rate.<\/p>\n\n

So everything is easy?<\/p>\n\n

By no means! We are already seeing an increase in the “steal now – decrypt later” scenario, in which attackers are already stealing your (company) data today in order to be able to decrypt it later using fast processes. <\/p>\n\n

Just imagine if I were to obtain an encrypted copy of your Bitcoin wallet today or the encrypted blueprints of your latest product. Even if I can’t decrypt it for another five years, that would be a problem for you and a successful break-in or theft for me. If there are technological breakthroughs sooner, all the better – at least for me. <\/p>\n\n

According to the agenda(https:\/\/digital-strategy.ec.europa.eu\/en\/library\/coordinated-implementation-roadmap-transition-post-quantum-cryptography)<\/a> of the EU Cooperation Group on Network and Information Security (NIS), all member states should start switching to post-quantum cryptography (PQK) by the end of 2026. The closer quantum computers come, the greater the danger of “steal now – decrypt later”. <\/p>\n\n

Cybersecurity is an ongoing issue and has become at least one more challenge thanks to new technologies. Sitting back and waiting is dangerous. <\/p>\n\n

P.S.: You may notice that I now cite sources in my posts. That’s because I’m starting to get suspicious myself (see my post https:\/\/www.linkedin.com\/posts\/stefan-wagenpfeil_informatikersindcool-menschenauch-informatikersindauchmenschen-activity-7334843650427805696-vJIU?utm_source=share&utm_medium=member_desktop&rcm=ACoAAAPRfmgBS2X4xsfduNSJJ9EDTbaovIvnGvk)<\/a> and want to give you an easy way to check.There’s unfortunately more and more scaremongering and bullshit or fake news on LinkedIn…. so feel free to make up your own mind! <\/p>\n","protected":false},"excerpt":{"rendered":"
