ABSTRACT:
Methods and devices for securely providing personalities to reconfigurable hardware. Reconfigurable hardware is provided with one or more domains. At least one domain serves as a gatekeeper domain and another domain serves as a task domain. A service provider provides an authentication and security personality to the gatekeeper domain. The hardware is shipped to the user. A user then accesses the service provider via a network connection and downloads a task personality into the task domain, but only if the personality in the gatekeeper domain allows the download to take place. Once the task personality completes a task, the user may download another task personality into the task domain, if permitted by the personality loaded in the gatekeeper domain. The domains and personalities are managed and made available by the service provider.
