Abstract
Techniques and apparatuses are described that implement the secure external data storage. A computing system may include a system-on-chip as a main processing complex and one or more secure elements that execute specialized functions related to sensitive information. While the secure element may use an external flash for storage for performance reasons, storing sensitive information on an external flash may expose the sensitive information if the external flash is ever compromised. The disclosed techniques and apparatuses provide an integrated secure element, of a system-on-chip, which leverages a secure channel with a secure flash to manage a cryptographic key for securing sensitive information stored on an unsecured external flash to prevent the exposure of sensitive information.
