Army eyes blockchain for trusted communications
To ensure that the data on which warfighters and their automated systems depend can be trusted, the Army's Space and Terrestrial Communications Directorate (S&TCD) is looking to novel technologies that will secure data flowing over terrestrial and satellite networks.
For its Information Trust program, S&TCD envisions technologies that leverages machine learning and blockchain for user authentication and sharing trust information. Specifically, it expects the system to have the following attributes:
- A machine learning-based service that identifies and blocks malicious structured and unstructured messages.
- A lightweight private blockchain that tracks the provenance of messages through the network and automatically detects message modification.
- Blockchain consensus algorithms that can be used in the field where bandwidth is limited and intermittent.
- A blockchain-based authentication service that tracks user trust values – compiled from machine learning, user/system data and network threat history -- and allows dynamic removal or addition of users to the blockchain during its lifecycle.
- An architecture that delivers real-time visual trust scores to the warfighter upon the receipt of messages or data.
The request for information was issued May 29, but a May 2 industry briefing said the Information Trust broad agency announcement would have an estimated value of $10 to $15 million between FY20 through FY24.
