    End to End Encrypted Communication - What Is It?

    You will have to send and receive the data during communication. A method that provides security while sending and receiving information during communication is an end to end encrypted communication. In this system, we encrypt the data on the systems or devices of the users. The intended recipients can only decrypt this data. The most important benefit of E2EE communication is that no one can read or tamper with the data. Facebook, WhatsApp and Zoom are the world's most famous messaging apps. These apps are providing end to end encrypted communication to the users. While adopting this system, they have to face some controversies. When you are using this system, you are confident that your communication is safe from the prying eyes. It is also the best way to ensure end to end encryption for financial transactions and business communication. 

    How Does End to End Encrypted Communication Work?

    To ensure the security of the users, they store cryptographic keys on the endpoints. These keys are helpful to encrypt and decrypt the information. We can use this technique for public-key encryption. Along with public, asymmetric and encryption keys, they also share private keys. If someone gets access to the public key, he/she can encrypt the message. Anyhow, if he/she wants to decrypt the message, he/she has to use the private key. We call it a decryption key. In online communications, we have to share information between two parties. 

    The first part is the server or telecommunication company. The second part is the user of the app or communication system. First of all, they check the legitimacy of the public keys. For this reason, they check that either this key is digitally signed or not. This key is widely used and known. Therefore, this key should be signed and presumed authentic. Secondly, there comes the recipient's key. Here, we will not see the sign of CA. Its reason is that it is a different key that has the same name. 

    How Does End to End Communication Differ from Other Encryptions?

    The endpoints of the end to end communication make it different from other types of encryptions. These endpoints are senders and receivers. The endpoints of this communication system can decrypt and read the information. Symmetric key encryption is also a unique feature of this communication system. It provides an unbroken layer for the encryption of the information. Anyhow, it is providing only one key for the encryption of the messages. The single key encryption is available in the form of a password, code or string. 

    They are present in the form of randomly generated numbers. In some cases, these keys may be complex. Anyhow, they can still pass the information from the sender to the receiver. These kinds of keys don't allow intermediates to get access to this data. Encryption in transit is also an essential feature of this communication system. By using this feature, the senders can encrypt the data. No one can read this message on the way. If someone wants to get access to this data on the journey, it can create some potential vulnerability on the way. Transit Layer Security is one of the most important examples of this kind of feature. 

    How to Use End to End Encrypted Communication?

    Recommended by a dissertation writing firm, we should use end to end encrypted communication where we require data security. The most important fields to use this communication system are healthcare, finance and communication industries. We can also use this system to comply with the data privacy and security regulations of the companies. It has become the must-have system for POS system providers. They have to protect the sensitive information of the customers. The retailer companies should also use this system. They can use the PCI DSS system because they can't store sensitive information on the devices of the clients. 

    Advantages of End to End Encrypted Communication:

    You can use end to end encrypted communication for various reasons. First, it is the best way to save your communication from the prying eyes. The senders and intended recipients can only read the information. It's because they have the encrypted keys to decrypt the information. Anyhow, the servers may also read the messages because they have to move the messages. Secondly, you can also use it to save your messages from tampering. The hackers don't have encryption and decryption keys. That's why they can't alter the messages. It can also save the metadata of your information. Thirdly, the hackers can't encrypt or decrypt the information without getting access to the endpoints. Some companies have to follow regulatory compliance laws. This kind of communication system provides encryption level data security to the users. 

    Disadvantages of E2EE Communication:

    Along with the advantages of end to end encrypted communication, there are some disadvantages of E2EE communication. First, we may find complexity in defining the endpoints. Some implementations allow encryption and decryption of the data at certain points. This thing makes it difficult for us to define the endpoints of the communication. Secondly, this system is providing too much security to the government agencies. Therefore, we may have to face lots of problems to get access to the content. Thirdly, it is providing security to the information. Anyhow, it is still showing the date and recipient. This thing can also provide some useful information to the hackers. Fourthly, it is not providing endpoint security. If someone compromises on the endpoint security, they can easily reveal the data. At last, it is not future proof. No doubt, it is using technology. Anyhow, quantum computing may replace this technology. 

    Conclusion:

    A system that provides security while sending and receiving information is the end to end encrypted communication. Facebook and WhatsApp are some famous apps that are using this communication system. If you will use this communication system, you can get lots of benefits. For example, it is the best way to save your messages from the prying eyes. You can also use this system to save the data from tampering. Anyhow, you may have to face some disadvantages. For example, you will have to compromise on the metadata. Moreover, you will have to compromise on the endpoints. Vulnerable intermediates are also a problem for the users. In the future, quantum computing may replace it.
