Abstract
A trusted communications environment includes a primary participant with a group creator and a distributed ledger, and a secondary participant with communication credentials. An Internet of Things (IoT) network includes a trusted execution environment with a chain history for a blockchain, a root-of-trust for chaining, and a root-of-trust for archives. An IoT network includes an IoT device with a communication system, an onboarding tool, a device discoverer, a trust builder, a shared domain creator, and a shared resource directory. An IoT network includes an IoT device with a communication system, a policy decision engine, a policy repository, a policy enforcement engine, and a peer monitor. An IoT network includes an IoT device with a host environment and a trusted reliability engine to apply a failover action if the host environment fails. An IoT network includes an IoT server including secure booter/measurer, trust anchor, authenticator, key manager, and key generator.
