Cryptographic ratchet
WebSince it was not possible to work backward from a later state to an earlier state and decrypt past messages, this technique became known as ratcheting; in particular, asymmetric ratcheting since it involves asymmetric (public key) cryptography. WebDouble Ratchet uses two cryptographic Ratchets, i.e., deriving new keys from current keys and moving forward, while forgetting old keys. The two Ratchets used are Diffie-Hellman ratchet and symmetric ratchet. Each time a Diffie Hellman ratchet move forward, a secret is established between sender and receiver using Diffie Hellman described above ...

A ratchet in the literal sense is a device that can only move forward in one direction, unable to move backwards. In the cryptographic sense, very similarly the algorithm can only advance state forward (i.e. is not reversible), but unlike the physical device, does not loop back around to an initial state.

WebOlm is an implementation of the Double Ratchet [10] cryptographic ratchet, created and used by the Matrix project. This implementation has been peer reviewed by NCC Group [11]. When E2EE is enabled every participant will establish an Olm session with ev-ery other participant. These sessions provide an E2EE communication channel WebJul 10, 2024 · The Olm algorithm is based on the Signal protocol, which means they achieve the same security properties as Signal does, while the Megolm algorithm is a new AES-based cryptographic ratchet developed for group conversations.
