Abstract: Examples of the present disclosure relate to an apparatus comprising interface circuitry to interface with one or more peripheral devices, processing circuitry to execute software to communicate with a given peripheral device of the one or more peripheral devices, trusted execution environment circuitry communicatively coupled to the interface circuitry and the processing circuitry. The trusted execution circuitry is configured to: receive a transmission from one of the processing circuitry and the given peripheral device to the other one of the processing circuitry and the given peripheral device; and apply a control policy in respect of the received transmission and, based on the control policy, determine whether to forward the received transmission to said other one of the processing circuitry and the given peripheral device.

Abstract: Systems, methods, and hardware devices for routing traffic between first and second electronic devices are arranged such that anonymities of the first and second electronic devices are maintained. This includes coupling the first and second electronic devices to a network having a plurality of routers, each of which includes a trusted execution environment (TEE) circuit. Each TEE includes a secure routing protocol, a routing table, and an attestation circuitry. Cryptographically secured channels are formed between pairs of the routers that terminate at the TEE. Each of routers executes an attestation procedure, and an ad hoc path is generated within the network based upon the secure routing protocol, the routing table, and the attestation procedure, wherein the ad hoc path includes a subset of the plurality of routers of the network. Traffic is routed between the first electronic device and the second electronic device via the ad hoc path.
