so so using brute force. what do you think how long you take to crack a RSA secret key lenght 2048 bits?That is not true. All traditional and current encryption is crackable because the stages of the encryption can be wiretap and supercomputer can used brute force to guess the key. It just take longer but eventually it will be crack no matter how many bits were.
The human factor always play a role but the human factor error is limited to turning the switch on and off. Because of the unique stage of quantum entanglement effect, the act of observing will caused the encryption information to collapse automatically. You can bribe the people working behind the quantum encryption but he or she won't know the information that is store in the encryption. It will be between the sender and receiver to know. The middle man, operator don't know and simply become a switcher. LOL
In traditional description, key is generated to bit of 0 and 1. For example, to encrypt letter B on a simple 8-bit which stand at 33 in the alphabetical system.
for 8 bit, you go
0 1 0 0 0 0 1 0
0 1 2 4 8 16 32 64
Here, you take 1 + 32 = 33 which is letter B.
No matter how many bit you put in, supercomputer can just run all different scenario to crack because bit encryption is transfer by the speed of light, which is constant. It is time consuming but eventually that unique key in that large number encryption will get crack.
Let me give you even a more simple example...Someone hide your son somewhere on earth, in a secret location of X,Y,Z. In traditional encryption, for you to find out the location of your son, you will need to find out which continent he was in, then which country, then which state, then which city, then which county, then which street. As you can see, you have to narrow down each step. Yes you will be able to get the information at the speed of light but still you have to ask and go step-by-step to find out.
In Quantum encryption, you don't need to take each step going at the speed of light to find out the destination. You can do so by asking all the questions at once. It will save you time and you get immediate answer.
don´t tell me you use quantum computer because such computer does not exist, unless you show me one.
no, key generation is usually based upon RSA, not so as basic and primitive as you showed it above. unless you show me it is chinese variant of key generation
so in quantum communication, the secret key is stored in the hardware. what differs to the current method of storing the rsa key in hardware, for example digital cinema?
