Resource access control in a system-on-chip ('SoC') may employ an agent executing on a processor of the SoC and a trust management engine of the SoC. The agent, such as, for example, a high-level operating system or a hypervisor, may be configured to allocate a resource comprising a memory region to an access domain and to load a software image associated with the access domain into the memory region. The trust management engine may be configured to lock the resource against access by any entity other than the access domain, to authenticate the software image associated with the access domain, and to initiate booting of the access domain in response to a successful authentication of the software image associated with the access domain.
