<P>PROBLEM TO BE SOLVED: To provide methods and apparatus for secure provision of access control entities (sSIM) after a host device on which the sSIM are used is deployed. <P>SOLUTION: Wireless user equipment is given a unique device key and endorsement certificate which can be used to provide a new eSIM to the user equipment in a "field". The user equipment can trust the eSIM delivered by an unknown third-party, based on a secure certificate transmission with the device key. An OS (operating system) is partitioned into various portions or "sandboxes". During operation, the user equipment is active and executes the OS in the sandboxes corresponding to a current wireless network. Partition packages are received while only the partition packages connected to the network are applied to the sandboxes. When loading the eSIM, the OS only loads a list of software necessary for a current run-time environment. Unused software can be subsequently activated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
