Abstract: Techniques for establishing a secure communication channel between a trusted portion of a system and another portion of the system and providing data over the secure communication channel are described herein. For example, a system may implement a Trusted Execution Environment (TEE) and a TEE component associated with the TEE. The TEE component may establish a secure communication channel with a Network Interface Controller (NIC) on the system, such as a smart NIC that is configured to encrypt/decrypt data and/or perform other operations. The TEE component may receive one or more cryptographic keys from a service provider and provide the one or more cryptographic keys to the NIC via the secure communication channel. The NIC may use the one or more cryptographic keys to encrypt data to send to another device, decrypt data that is received from another device, or otherwise encrypt/decrypt data.
