The basics of creating a VPN authentication, strong encryption, and secure method Key Exchange is to authenticate users with the secure exchange of encryption key and then encrypt the data using the generated key.

If you also would like to have an authenticate key to investigate this website (also called 이 웹 사이트를 조사하십시오 in the Korean language) and accomplish your work securely.

Authentication is used to validate the identity of users uses one or more of a number of methods:

Something You Have:

It can be a key card, security pass, driver’s license, passport, or similar. Ownership of one of these items is usually sufficient to confirm the identity of the holder. The problem with this is that the device is lost or stolen, and sometimes used by others.

Something You Know:

Password, passphrase, or other known information that can be used to calculate the function of a secret message.

Encryption systems must use complex mathematical algorithms so as to provide a good deterrent than an attacker to be able to use some brute force method of calculation algorithms. Two common methods of encryption are Symmetric Encryption Systems and Public Key Encryption Systems.

The symmetric encryption uses the same key for encryption and decryption of the plain text of the ciphertext and decryption at both ends. Encryptor key applies to plain text data that generate the ciphertext. Decryptor reversed it by applying the same key to the ciphertext to reveal the plain text data.

Public Key Encryption systems are much more complex than symmetric encryption system such as DES and depend on a mathematical function that is often referred to as a “trap door” function. The algorithm generates the encryption mechanism and the encryption key that can be made public and the decryption algorithm and a decryption key that is kept secret. The mathematical algorithm is so complex that it is not possible to deduce the decryption mechanism of encryption mechanisms alone.
