SigNet by Armour
SigNet by Armour is an alternative to their flagship product Armour Mobile, developed to suit specific security and operational requirements. SigNet provides secure voice, video, messaging, group chat, file attachments and Message Burn (timed messages) with AES-256 bit encryption, with an on-premises option for total privacy and no auditability. SigNet provides the same ease of use as consumer grade apps and is available for Android and iOS devices and for Windows 10 and Mac OSX desktops. This new product line will run concurrently with Armour Mobile.
SigNet uses a peer-to-peer key management system, specifically a double ratchet algorithm with pre-keys and 3-DH key management to provide confidentiality, integrity, authentication, participant consistency, destination validation, forward secrecy, future/backward secrecy, causality preservation, message unlinkability, message repudiation, participation repudiation, and asynchronicity.
