Interdasting. Linky, please?
The simplest example would be XOR encryption.
This elementary method is unbreakable. Decryption is only possible with the key. There is no way to generate the key if all you have is the encrypted data.
The method has drawbacks, the key length is equal to the length of the encrypted data. This is mitigated by the existence of cheap and large uSD cards.
Like all secret-key methods you are hampered by the key-exchange problem.
With XOR encryption all possible keys for a given file are equally valid thus there is no way to decide which decryption is the intended one...
The XOR method depends upon the ability to create quantum random numbers... this is easy now but was once difficult. The German Enigma machine was an XOR device that depended on a mechanical means to generate random numbers...the problem is that no mechanical method can produce true random numbers and no software can either. It requires a quantum event like diode noise, Brownian motion or radioactive decay..etc
At this time there is no public-key encryption method that can be said to be forever secure. This is a pity as public-key is so handy.
XOR encryption is totally secure so long as the key is at least equal in length to the data to be secured and the key is made up of truly random numbers. When these conditions are met you have what is known as a one-time-pad which has long been deemed unbreakable. You must also never encrypt more than one file using the same key.
IMO, it will be a nearly impossible task for quantum computers to break a well-designed symmetric algorithm such as AES. The best known attacks against modern symmetric methods can at best only weaken the methods slightly... good keys of sufficient length will become more and more important as time marches on...
Is it verified?
Not as far as I can tell.
Sound like another boastful BS claim, to me.
Show us, ChiCommie scumbags!
The Chinese also claimed during the Great Leap Forward that they improved agriculture techniques so much that their fields were yielding 10000 kg of wheat per “mu” which is about 1/6th of an acre.
Even the most advanced farming technology in the US today can only produce about 1500 kg per acre. which is about 250 kg per “mu”.
bkmk
Well, that and five bucks will give you a cup of coffee at Starbucks.
