The need for openness in mobile handset platform architectures from an applications development perspective, with a conflicting need for closedness in such platform architectures for security, manageability, and multiprotocol communications processing, has created a need for an overall platform architecture that provides simultaneous support for such features. Platform architectures are suggested that are rooted in hardware along with a trusted platform-aware architecture manager that creates closed partitions to provide cryptographic, communications, and manageability services, as well as open partitions for applications processing. Important and desirable ingredients in such platform architectures include domain separation, hardware rooted mechanisms to establish platform trust, hierarchical key management, secure storage, efficient resource management, and an inherently manageable platform
