Original Abstract Submitted

Techniques for implementing and enforcing a security policy in a secure element are disclosed. The secure element enforces the security policy to grant and/or deny access, such as from an application processor, to configuration of the device peripheral components and access to data of the device peripheral components across one or more bus architectures, such as an I3C bus. Implementing an access control policy in a secure element allows execution of code within the isolated secure element hardware processor, preventing software attacks that may emanate from code running in the application processor. This design also benefits from hardware protections against physical attacks.
