00:00Does the Internet have an expiration date?
00:02Google says by 2029 the digital world could change completely.
00:06The reason?
00:07Q-Day.
00:08That's what experts call the moment when quantum computers are able to crack the encryption
00:12that keeps the Internet safe.
00:14Think of a maze for a second.
00:16A normal computer tries one path at a time, while a quantum computer explores all paths
00:21at once.
00:22That capability makes them very fast.
00:24In May, a Chinese quantum computer reportedly set a new speed record in a particular task.
00:29It completed an extremely complicated calculation in 25 microseconds.
00:34The world's fastest supercomputer would need a 3 decillion years to solve the problem.
00:39That's the one with 42 zeros.
00:41Please note, this benchmark was reached in a test setting and does not mean quantum computers
00:46can already crack today's encryptions.
00:48But it shows the technology is evolving at a breathtaking pace.
00:52What does that mean for cybersecurity?
00:54Who's at risk?
00:55If quantum computers could break current encryption, a lot would be exposed.
01:00First, national security and infrastructure.
01:03Think of power grids, transport systems, or military communication.
01:07With a quantum computer, bad actors could in theory weaken a country's vital infrastructure.
01:12Second, the global economy.
01:13Global banking and crypto heavily rely on encryption.
01:17A single hack could cause losses in the trillions of dollars.
01:20And finally, you.
01:21Every private DM, bank password, and medical record encrypted at the current standard would
01:26be vulnerable.
01:27Sounds scary, but how real is the threat right now?
01:32Okay, let's not panic too much for now.
01:34Cybersecurity companies love talking about Q-Day, because fear helps them sell new quantum-safe
01:40encryption.
01:41Apart from that, Google has published a timeline for making its operating system Android quantum-resistant,
01:47promoting themselves as a trustworthy player for the future.
01:50But the threat is real, and we have already reached the preliminary stage.
01:55Hackers are stealing encrypted data.
01:57Even if they can't read it yet, they're storing it, waiting for quantum machines to
02:01catch up.
02:02When that happens, old data could become readable overnight.
02:05The phenomenon is already so widespread that there's a term for it.
02:09Harvest now, decrypt later, or HNDL in short.
02:13So, are we just doomed to face a digital apocalypse?
02:17Not exactly.
02:18There's a global push to switch to PQC, post-quantum cryptography.
02:23New encryption designed to resist quantum attacks.
02:25These are ultra-complex mathematical riddles that even quantum computers can't easily untangle.
02:31And the push is not just coming from the private sector.
02:34Governments are starting to set deadlines and restrict software that won't hold up in
02:38a quantum future.
02:39So the race is officially on.
02:41What do you think?
02:43Can tech engineers rewrite the security DNA of our online services before Q-Day arrives?
02:48Let us know.
