Abstract
A runtime security system, including: a shared core configured to execute processes having varying levels of trustworthiness configured to receive security services requests; an execution monitor configured to monitor the execution of the shared core further comprising a timer, a policy table, and an execution monitor state machine; secure assets including cryptographic keys; and immutable security service functions configured to enable access to the secure assets in response to secure services requests; wherein the execution monitor is configured to: detect that the shared core has received a secure boot request; verify that the secure boot request is valid; allow the shared core to securely boot when the secure boot request valid.
