SIMBA: Secure Messaging on the Blockchain Architecture

The secure messaging on a Blockchain architecture (SIMBA) project will architect and design a decentralized mobile peer-to-peer, end-to-end, secure messaging application that uses Blockchain technology. We aim to build SIMBA from the Fabric (Open Blockchain) implementation due to its novel approach to smart contracts using chaincode services and several other features including membership, consensus and identity management and flexible distributed ledger implementation. We identify several extensions to support secure messaging and smart contracts including the use of mini containers for smart contracts, a data transaction layer to support messaging and their access, and the ability to seamlessly move Fabric onto mobile ad hoc networks through the use of a UDP-based transport mechanism. By building on ITAMCOs CryptoChat technology, connecting it to a Web app and the Fabric API, we will provide a platform for delivering secure messaging and other messaging features including: the ability to interface with smart contracts, send files, and even send Docker containers securely across the underlying blockchain infrastructure. The SIMBA mobile phone app and Web dashboard act symbiotically, mirroring and synchronizing content as the user moves seamlessly between them resulting in a flexible and powerful decentralized secure messaging infrastructure to meet the DoD needs.
