Clusion v0.2.0

by Seny Kamara and Tarik Moataz Over the last two years, we have been working on an open source encrypted search library called Clusion. We are using it in several ESL projects, including the Signal Search project we recently released. We are also excited that other groups are experimenting with it. In this post, we wanted to give an overview of Clusion and answer some of the most frequently asked questions we have received about it.

Signal Search

by Joe Engelman, Seny Kamara, Tarik Moataz and Sam Zhao. Overview Signal is an end-to-end encrypted messaging app made by Open Whisper Systems. It is based on the Signal protocol which was designed by Trevor Perrin and Moxie Marlinspike. In addition to underlying the Signal App, the Signal protocol is also used by WhatsApp, Facebook Messenger and Google Allo. Why is Signal important? Together with PGP-encrypted email and OTR-based messaging, the Signal App is one of the most secure ways to communicate.
