The document discusses securing data rather than networks by encrypting data once at its source and maintaining that encryption as the data passes through networks of varying bandwidth capabilities. This approach allows data to be used over any network while avoiding issues with dropped secure connections or lost devices. Challenges include maintaining end-to-end encryption as network bandwidth fluctuates, but the proposed approach uses open interfaces and standards-compliant solutions to optimize encrypted data transmission across network changes. Potential applications include CCTV, vehicle communications, drone communications and satellite connections.
