Understanding Telegram's Security Mechanism > 자유게시판

Telegram has become one of the most popular messaging apps in recent years, offering total encryption for its users. With the rise of digital threats, encryption has become a topic of interest for many people. In this article, we will delve into how Telegram's encryption mechanism works and what advantages it offers.

What is Encryption?
-----------------

Encryption is the process of translating plaintext data into unreadable decoded text to guard it from unauthorized access. There are various encryption techniques, including asymmetric methods.

Telegram's Encryption Method
---------------------------

Telegram uses a hashing encryption method to secure its data. This method involves generating a uniform secret key that is used for either encryption and decryption. The key is produced using the Advanced Encryption Standard (AES) algorithm, which is considered secure.

Here's a simplified explanation of how Telegram's encryption works:

1. When you create a chat or send a message, Telegram produces a unique symmetric key for that conversation.
   
2. This key is used to encrypt your message, producing it unreadable to anyone without the key.
   
3. The encrypted message is then transmitted to Telegram's servers, where it's saved.
   
4. When the recipient receives the message, Telegram translates it using the same symmetric key.
   
   

End-to-End Encryption

----------------------

Telegram offers complete encryption for its Private Conversations feature. This means that only the sender and the recipient can read the messages, and even Telegram's servers cannot view the encrypted data.

Here's how Telegram's Secret Chats encryption works:

1. When you initiate a Secret Chat, Telegram produces a unique symmetric key for that conversation.
   
2. This key is encoded using the recipient's public key, which is preserved on their device.
   
3. The encrypted key is then forwarded to the recipient's device.
   
4. The recipient can then decode the key using their private key, and use it to encode messages to the sender.
