The Double Ratchet Algorithm is a protocol (similar to OTR) that provides for
|
|
perfect forward secrecy in (a)synchronous communications. It uses triple
|
|
Diffie-Hellman for authentication and ECDHE for perfect forward secrecy. The
|
|
protocol is lighter and more robust than the OTR protocol - providing better
|
|
forward and future secrecy, as well as deniability.
|
|
|
|
The protocol was developed by Trevor Perrin and Moxie Marlinspike. Its chief
|
|
use currently is in the Open Whisper Systems Signal package.
