During the planning phase of a military operation, there are multiple text documents that need to be updated simultaneously by multiple users. At the same time, there is a requirement to provide security in air-gapped deployments. As such, a solution that follows high standards for security, performance and quality is required. Within my presentation, I will be describing an embedded solution based on advanced operational transformation algorithms which allows real-time secure collaborative editing, as well as several challenges that we have faced during development and how we managed to overcome each of them.
