Abstract
Techniques are described herein for applying access controls to logical secure elements (LSEs) running on the same secure element hardware platform. Embodiments include a firmware component that determines whether a message targeting an LSE is authorized to trigger an operation. For example, the firmware component may verify a signature of the received message using a public key, shared secret, or other access control key. Additionally or alternatively, access control policies may be defined to constrain the load of the LSEs on the SE platform hardware and/or to prioritize LSE access. For example, the access control policies may define usage thresholds, such as maximum threshold memory and/or processor utilization rates. As another example, the access controls may restrict the active time for an LSE to a threshold duration. If access constraints are violated or the message cannot be verified, then the firmware component may delay or deny the operation.
