Abstract
A mobile communication device. The mobile communication device comprises a verification application, when executed by a trusted security zone portion of the processor, examines an integrity of a preloaded open mobile alliance (OMA) device management (DM) payload, wherein a security key in the OMA DM payload is compared with a security key stored in the trusted security zone to determine the integrity of the OMA DM payload and to determine the state of a preloaded first operating system from a first network. The verification application further verifies the identification of the mobile communication device, transmits information comprising the security key in the trusted security zone to a server to verify network provisioning of the mobile communication device, and changes the toggle key based on the verification results, whereby asset migration between network carriers is achieved and unauthorized activities are avoided while security keys are kept confidential to individual carriers.
