The term "end-to-end encryption" originally only meant that the communication is never decrypted during its transport from the sender to the receiver. [9] For example, around 2003, E2EE has been proposed as an additional layer of encryption for GSM [10] or TETRA, [11] in addition to the existing radio encryption protecting the communication between the mobile device and the network infrastructure.
In contrast, Apple’s end-to-end encryption only applies if everyone you chat with is also using an Apple device. This means that as long as one person in your group chat is using an Android ...

The entire communication via Threema is end-to-end encrypted. During the initial setup, the application generates a key pair and sends the public key to the server while keeping the private key on the user's device. [21] The application then encrypts all messages and files that are sent to other Threema users with their respective public keys.
Hardware-based encryption is the use of computer hardware to assist software, or sometimes replace software, in the process of data encryption. Typically, this is implemented as part of the processor 's instruction set.
[37] [38] In March 2019, Google discontinued Allo in favor of their Google Messages app on Android. [39] [40] In November 2020, Google announced that they would be using the Signal Protocol to provide end-to-end encryption by default to all RCS-based conversations between users of their Google Messages app, starting with one-to-one ...
A mechanical ratchet. The Double Ratchet Algorithm features properties that have been commonly available in end-to-end encryption systems for a long time: encryption of contents on the entire way of transport as well as authentication of the remote peer and protection against manipulation of messages.
ChaCha20-Poly1305 is an authenticated encryption with associated data (AEAD) algorithm, that combines the ChaCha20 stream cipher with the Poly1305 message authentication code. [1] It has fast software performance, and without hardware acceleration, is usually faster than AES-GCM .
