Session management framework for secure communications between host devices and trusted devices

Abstract:

Embodiments are directed to a session management framework for secure communications between host systems and trusted devices. An embodiment of computer-readable storage mediums includes instructions for establishing a security agreement between a host system and a trusted device, the host device including a trusted execution environment (TEE); initiating a key exchange between the host system and the trusted device, including sending a key agreement message from the host system to the trusted device; sending an initialization message to the trusted device; validating capabilities of the trusted device for a secure communication session between the host system and the trusted device; provisioning secrets to the trusted device and initializing cryptographic parameters with the trusted device; and sending an activate session message to the trusted device to activate the secure communication session over a secure communication channel.
