Cryptography is the race between advanced algorithms one create codes and the other break codes.

The image above is "the lattice cryptography relies on mathematical lattices — arrangements of dots in space". (Quantamagazine.com/ Cryptography’s Future Will Be Quantum-Safe. Here’s How It Will Work). The image could also introduce the model of cryptography where the system breaks information into pieces. And then it sends that data to the receiver by using different routes. 

The fact is this. Quantum cryptography seems invincible technology that turns cryptology into history. But then another fact is that also all other encryption methods seemed invincible when they were introduced to users. And sooner or later, there is found some kind of vulnerability. 

When cryptographical systems develop, developers use technology that is best in business at that time. And that thing causes mistakes. 

And that is a problem with the encryption process. Faster and more advanced computers can break the code. And there is a possibility that advanced systems can break even quantum cryptography. 

The idea is that if a qubit travels across two laser rays or quantum channels. The first laser steals information. And the second one will make the replacing qubit. So the system just reads information from the qubit. And then it will make the new qubit. 

The power of quantum cryptography is that the information is stored in a solid piece. That piece is the electron or photon. And that makes it almost impossible to read information from that qubit. The system detects if the qubit is lost or its energy level is changed. But there is the possibility that the attacking system can make a copy of the qubit.  

Systems are safe if they are done as they should.  If the qubits are not protected that can cause a situation where some kind of laser system can steal information and copy the qubit. So in that case the system cannot detect the missing qubit. But that is only theory. And the theory is a path to a practical solution. 

Even if algorithms cannot break codes or lasers cannot steal qubits there are always people working with systems. The attackers can use bribery, sodium pentothal, or some other method to make people give information. And that means there are always vulnerabilities.

The problem with quantum communication is how to make systems understand each other.

In old fashion encryption, the sending system decodes the message by using the precise key. That key is the coin in this text. Then the receiving system decrypts the massage by using the same key that the sender uses but oppositely. If the sender encrypted the ASCII codes by using multiplication. 

The receiver will divide the ASCII codes by using the same encryption key. In the quantum system, the sender uses a certain group of encryption keys. The idea is that the sender doesn't know precisely which encryption key it uses. But the system knows that in the number of the keychain it used. 

But the sender doesn't know which number the "keychain 2" is in the receiving system. That thing makes it harder to capture the key. Each encryption key in the keychain has a certain value. In the next text. The keys are handled as physical tools like coins. So each coin is a certain key. Those values are the material (frequency), color energy level, and many other things. In the case of qubits the electron, photon, proton, and electromagnetic radiation can be used as values that are telling the system is a message meant to it. 

If we compare the toss of a coin with the encryption process we can think that sending and receiving systems are tossing the coin. If the sides of the coin are the same. Those systems are in the same frequency. And the information can travel between those systems. The problem is how to make sure, that the sides of the coin are the same.

The image above is a good example of the problems with quantum encryption. In that model, the persons toss the coin. If both of them will get the same side another system is ready to receive the message. If the sides of the coin are different. The systems will not match. So in the case, that the sides are different the receiving system thinks that message is for somebody else. And it will not try to open it. 

One of the biggest problems is how to send the key to the receiving system. Or how to make the coins match between systems? There can be billions of coins in the system. 

Those coins or keys might look the same. 

But they can be different. 

The material of those coins can be different. One coin is made by using bronze. 

The second one is made of nickel. And the third coin is made of ice. There are rules of the systems regarding which material they should accept, and which value of the coin is acceptable. And of course, things like impact power and other things can use as encryption value. 

Also, the time when the coin is sent can make the key more complicated. So the time stamp of the coin can tell if the message is meant for receiving system. So in this system, every coin is the qubit or encryption key. 

In quantum systems, the system uses uncertain principles for encrypting and decrypting the message. The system can give the keychain to encrypting tool. And then the encryption system selects one key at random. After that, the sender sends the message. And then the receiving system will know which keychain it must use. Then the system will try all keys together. 

The thing that makes quantum computer superior is that they can handle at the same time multiple keys. In that case, the system uses multiple keys that are used at the same time. And that makes quantum computer superior. 

The Bird Is Gone

The Bird Is Gone

Could there be an encrypted message where is letters T.B.I.G (The Big) (Terminating Big) and could that mean some kind of demolition device?

What does this message mean? When we are thinking about this message it has been found on the tree, what is in one of the farthest and most isolated islands in the world. Sometimes I have thought is some carrier pigeon left to home for sending a message, and then something happened to that bird. At first, we might think, that somebody was mistakenly released some carrier pigeon, but there is another explanation. 

Is that the very well encrypted message? But is the message some kind of encrypted thing, where are the hidden word "The BIG", if we would take only the first letters of the words. So is there some special bag or something else? Those letters are T.B.I.G, what might mean that there has been happened something big. or T.B.I.G might mean (T) BIG, what might mean "Terminating Big". And is that "terminating big" some kind of demolition equipment. 

Or was there some dead bird laying on the rock. And then someday the persons, who have left that message suddenly have seen that "The Bird is Gone", so there is one little bit more interesting explanation for that message, and could that some ship, what name was "The Bird" was gone. Or did somebody accidentally released some kind of bird as an example carrier pigeon?

Is this "Bird Is Gone" message the key to the mystery of treasury, what is claimed to hide on that island? And how the maker of that message hoped, that somebody will find it?

Above this text is a message, that somebody has sent to a tree on the Cocos island, and that message could be the key to the treasury mystery, what has been told about that island. In that island is claimed to be the treasury, but nobody has been officially found it. When we want to solve some problems, we must think about what is the simplest possible reasons for that thing. When we are looking at things, what we might think as clear, we might find another meaning for the things, what seems regular. So when we are looking like the stories of the lost treasure, we must ask, why somebody wants to hide that thing? If some pirate would hire treasury to the beach a long way from home, how that person would think to return and get the treasury? 

Does that pirate rent a ship, and then go to get that thing from the sunny island? But if the treasury is gold and diamonds, why that pirate would not melt gold, and claim to find jewelry, and sell them to some store? So what that treasury could be? Are they some kind of documents, what is proving about some kind of cooperation with some investors and pirates, and this kind of thing might cause that the pirate could buy himself free from the prison if that person would someday catch because somebody has become suspicious of the origin of the money of the old sea captain.
