What is End-to-End Encryption (E2EE)?

November 27, 2019

Basically, end-to-end encryption is an implementation of asymmetric encryption. It protects data so it can only be read on the two ends: sender and recipient. This means that every single bit of data is transferred with a special key that scrambles data. That’s why encryption is an implementation of cryptography.

Cryptography is the art of writing the code which is used to generate the codes that keep the information safely encrypted. Decrypting the encrypted data is impossible for third parties. Only the recipient with the corresponding key can unscramble the data. 11Sight uses end-to-end encryption on every platform to keep your data safe.

Data from applications are mostly stored in a server. If the messages are stored in the server of the application service provider, it’s possible to share them with third parties. If your messages are not encrypted when sending to the recipient, it’s more likely to be used by third parties.The security of data depends on the company that owns the application.

Thanks to end-to-end encryption your messages, photos, videos, voice messages, documents, status updates and calls are prevented to be used by malicious users. Encrypted data cannot be read by anyone, including the application’s owner. The key to open the scrambled data is only available at the sender and recipient. For extra security, every message sent has its very own code. It’s not possible to solve even if the server information is seized. Sometimes malicious users make false applications to capture information. It’s important to make sure that you are using the original application to ensure your data is being encrypted.

The two types of end-to-end encryption are symmetric and asymmetric. In asymmetric encryption the general key is mostly a string that is random, unique and single-use; and it can be used by everyone and every computer with the purpose of encrypting and sending to recipient. Symmetric encryption states the situation where only the ones who have the private key can solve the code. Besides, there’s only one key that is shared.

Every digital data can be stored, like e-mails, photos, credit card information and documents. The easy way to encrypt all data at once is to use a VPN connection and send sensitive information via this connection. Even if this method is not as safe as end-to-end encryption, it prevents the data from being sniffed on unsecure Wi-Fi networks.

Is it really safe?

By purpose, this method ensures the “message” is kept between the sender and the recipient and prevents third parties from reaching it. However, sometimes it causes illusion amongst users. Such that, the thought of “nothing can be kept private” causes worrying and misunderstanding. 75% of users attended in the surveymade in England indicate that they think “this encryption is method is not safe and third parties may access sensitive information if they want”. Worrying about sensitive issues is natural but it should be underlined that end-to-end encryption is extremely safe. Even if you are exposed to malicious software and viruses, the data will be safe. Because the data is encrypted at the device and not the server; applications are not able to decrypt this data.

Is it available on every platform?

It’s not easy to implement end-to-end encryption method on every platform. The hard thing about using this method on every platform is to encode and decode the keys and accord them on both sides of communication. As 11Sight, we care about your data privacy and use end-to-end encryption on every platform.
