#What is encryption?

Encryption isvery important for seculity systems.Current line to go through a lot of bases.

Encryption is change the data to code before the communication.And sever will decryption the code in order to read. If only this explane you may not understand what we say. Simply say, It is to prevent peeping from outside. If there is no encryption,people can steal information easily from relay bases.

Some people say "No problem!". But if there is no this system, third party can steal a lot of information. Forexample,paesonal data, your cards information and your address!
NEXT>> we are explane about construction of encryption!


#Construction of encryption

Encryption system need key and lock. We will explane about how to encryption with key and lock following next example.
First, I assume you will shop online. At that time, you will input your card number on the form. If leak your card number,you will get a lot of dameges. How do enterprises use locks and keys to protect customer's personal information? Think about it before you read.

The enterprise side has to pass the information of the key to the customer without leakage. For that purpose, the enterprise side first sends a available lock　to the customer side.And the customer closes the lock key with the important personal information inside. Then, there is a key on the company side, so information can not be stolen at the relay point. In this way, in order to protect important information, Encryption method is indispensable in the current Internet society.(Figure↓)



#What is computer's key？

As explained earlier, we keep confidentiality by encrypting communication contents during communication.So what kind of thing is used for Encryption? For Encryption of communication contents,mainly use mathematics. Do you know this type of formula.299=13×23　This formula is an expression that prime factorizes 299 into 13 and 23. It sayRSA encryption.This cipher is key 299, safe (lock), 13 and 23 are key.

In other words, we will send the communication contents in a safe called 299 and send. In order to open the safe it is necessary to have prime numbers 13 and 23. In this way information communication is Encrypted.However, even if you can not solve a cipher that can not be solved by a conventional computer, it is not so if you can solve it with a computer of the future.

New computer's name isQuantum computer. Since the structure of this computer is very difficult, I will leave it out this time, but to make it impossible to calculate with the current computer,             Please think that it is a super high performance computer. Let's say that you solve the RSA cipher that you talked about earlier on a conventional computer. At that time, we assume it will take tens of thousands of years. Can you use only traditional computers and solve this code?

No, you will not. So it is used as a safe Encryption that can not be broken. However, it is expected that when you solve it with a quantum computer, you can solve it in a few hours. Safety can not be maintained if it can be solved in a few hours.Therefore, we must develop a new code.（It takes tens of thousands of years to solve quantum computers） And now, many engineers are searching for new encryption. In this way, information technology develops.

#Our opinion

The computer 's Encryption is currently at stake.Because a new computer called Quantum Computer appeared. Quantum computers have far higher computing power than current classical computers. By doing this, the possibility that the defense by the prime number will break through has come out.

If the technology of Encryption is invalidated the world will definitely get into confusion. In order to prevent this, engineers from various countries desperately have developed a new Encryption method.In this way, technology is evolving every day in the information society. Why would not everyone study the latest technology in various ways?
