Multi-Device for Signal
Multi-Device for Signal S´ebastienCampion3, Julien Devigne1, C´elineDuguey1;2, and Pierre-Alain Fouque2 1 DGA Maˆıtrisede l’information, Bruz, France [email protected] 2 Irisa, Rennes, France, [email protected], [email protected] Abstract. Nowadays, we spend our life juggling with many devices such as smartphones, tablets or laptops, and we expect to easily and efficiently switch between them without losing time or security. However, most ap- plications have been designed for single device usage. This is the case for secure instant messaging (SIM) services based on the Signal proto- col, that implements the Double Ratchet key exchange algorithm. While some adaptations, like the Sesame protocol released by the developers of Signal, have been proposed to fix this usability issue, they have not been designed as specific multi-device solutions and no security model has been formally defined either. In addition, even though the group key exchange problematic appears related to the multi-device case, group solutions are too generic and do not take into account some properties of the multi-device setting. Indeed, the fact that all devices belong to a single user can be exploited to build more efficient solutions. In this paper, we propose a Multi-Device Instant Messaging protocol based on Signal, ensuring all the security properties of the original Signal. Keywords: cryptography, secure instant messaging, ratchet, multi-device 1 Introduction 1.1 Context Over the last years, secure instant messaging has become a key application ac- cessible on smartphones. In parallel, more and more people started using several devices - a smartphone, a tablet or a laptop - to communicate. -
