RE: Bitcoin Security Overview & Quantum Computers
Interesting! But how can you know that 160 bit is secure enough while quantum computers are not invented yet? Is it already known how much computing power they will deliver?
Many cryptographic experts agree that it's impossible to crack it with quantum computers. It has to do something with the alhogithm they work with, since qc can only crack certain algorithms faster, while on others they are not better than normal computers. So quantum computers are not that dangerous as they sound, they were hyped up too much by silly documentary movies.
This is interesting, and a bit reassuring. I always just assumed that quantum computers would be able to brute force pretty much any kind of encryption that we have right now, but I've never researched the subject. Can you provide any sources for this that would be easy for someone without much knowledge of the subject to understand?
Nah, its just those stupid documentary films on television that exxagerate this phenomena, it's nowhere near the threat they hype it up to. Quantum computers are only better for certain algorithms but for others its quite slower. It doesnt crack passwords instantaneously, it just finds more efficient ways to crack them, and for some algos there aren't.
I dont know about resources you might want to check out stackexchange.com questions on encryption, there are people there who quote research papers that are easy to read.
Thanks, I can see this is a subject that I should get to know more about. I used to really be into science reading but haven't had much time for it lately. This would be a good way to get back in the habit.
