Various embodiments provide methods and computing devices configured to implement the methods for the dynamic generation of a value that may be used to protect a communication based on the dynamically changed ephemeral shared data set. Various embodiments incorporate the assumption that trusted systems ultimately are demonstrably insecure, because such systems are penetrable and vulnerable. Various embodiments provide a digital communication system that assumes no trust among various network elements, for at least the reason that the digital environment is inherently untrustworthy. ## Claims ### Claim 1 A data set management device for managing synchronization of an ephemeral shared data set stored at a first computing device and a second computing device, comprising: a memory;
