What is end-to-end encryption (E2EE Full Form)?
End-to end encryption (E2EE Full Form), is a method to secure communication that prevents third-parties from accessing data when it’s being transferred from one end device or system.
E2EE is encrypted data that the sender has set up on their device. Only the intended recipient can open it. The message can’t be read or altered by any internet service provider (ISP), app service provider, hacker, or other entity as it travels towards its destination.
Many messaging services, such as Zoom and WhatsApp, WhatsApp Web use end to end encryption. These providers have faced controversy around the decision to adopt E2EE. This technology makes sharing user information with authorities more difficult and could allow for private messaging to criminals.
How does end-to-end encryption work?
The endpoints contain the cryptographic keys needed to encrypt or decrypt the messages. This approach uses public key encryption.
Public key or asymmetric encryption uses both a public and private key. Once the public keys are shared, anyone can use them to encrypt messages and send them to the owner. The decryption keys are required to decrypt the message.
Online communications almost always have an intermediary who relays messages between two parties. The intermediary is typically an ISP server or a telecom company. The intermediaries can’t listen to the messages being sent because of the public key infrastructure E2EE.
A digitally signed certificate by an accredited certificate authority (CA) can be used to verify that the public key is authentic. Because the CA’s publicly available public key is well-known and widely distributed, it can be trusted that its veracity has been verified. Therefore, a certificate signed using this public key can be assumed to be authentic. Because the certificate is associated with the recipient’s name and public keys, it is unlikely that the CA would sign a certificate affixing a different public key to the same name.
