Quantum Computers
#1
Hey Everyone,
So,m Quantum computers are coming. You can say that they are already here. What does it means for cyber security? How we gonna be safe with classical computer encryption. I was searching about the ideas to be safe in that state. Quantum itself provides a better options for encryption. Something to do with observer phenomenon. Let me know what you think about the Quantum information age.

Most algorithms have been updated to account for the massively increased computation power that quantum computers. It's why we've seen the increase in 4096 bit ciphers and browsers require the larger ciphers.

But in the case of Quantum computers, It's doesn't matter how bigger the key or bit cipher you used. In case of quantum any encryption key can be cracked within few secs .

yes you are right.. Hope we can get our hands on these computers in our lifetime.. Smile

Sorry to discourage you, but so far they only managed to speed up the process of calculating 4kB of data within the time of a regular computer with 1kB. Still 4x faster but noway near the speed for decrypting shit.
And if Quantum computers surface, then quantum computing encryption also surfaces! So in terms of encryption you'll be safe.

meh... I think encryption is safe. Then again who knows what shit the NSA is hiding and or working on.

always presume that someone with money and time will hack you.
The only thing you can do is slow them as much as you can. The NSA can probably hack you, but "common" pirates can't afford a quantum computer.
And if so, quantum computers are not available for people like us and for now not powerful enough to crack 2048 or 4096-bit keys.
You'll pretty safe for now, in 5-10 years, who knows...

Quantum computers are a couple decades off, or longer.

Lots of encryption, VPNs, hashes, keys, and passcodes will get cracked.

Its a big game - bigger computer, better algorithms.

everything will be the same. nothing will change. only new word quantum will appear in the sentence....

This is just another bundle of exploits ready to be raped, I believe that similar to the IoT botnet these computers will have a vuln that will make them a super contributor to a botnet added a lot of brute force power to security.
