Title: TRUSTED PLATFORMS USING MINIMAL HARDWARE RESOURCES
Abstract:
Systems and methods facilitating a framework that provides a core trusted computing base (TCB) of an electronic device with various security capabilities. The framework can include a low-resource device and at least one distributed resource. The low-resource device can be configured to generate sealing keys, migration keys, and attestation keys that are based on a device secret associated with the low-resource device and one or more software modules. The low-resource device can further be configured to use the migration keys and the sealing keys to both verify a software update and migrate secrets from a previous version of the software to a newer version of the software. Additionally, the low-resource device can be configured to generate an attestation statement using the attestation keys and perform attestation using the attestation statement and the at least one distributed resource.
