Abstract: A system that incorporates the subject disclosure may include, for example, instructions which when executed cause a device processor to perform operations comprising sending a service request to a remote management server; receiving from the management server an authentication management function and an encryption key generator for execution by a secure element and an encryption engine for execution by a secure device processor, sending a request to establish a communication session with a remote device; and communicating with the remote device via a channel established using an application server. The secure element and the secure device processor authenticate each other using a mutual authentication keyset. The secure element, the secure device processor and the device processor each have a security level associated therewith; the security level associated with the secure device processor is intermediate between that of the secure element and that of the device processor. Other embodiments are disclosed.

Abstract: A system that incorporates the subject disclosure may perform, for example, receive secret information and non-secret information from a secure download application function, provide a request for a first verification to a secure element where the first verification is associated with access to content and/or an application that is accessible via the secure download application function, receive the first verification which is generated by the secure element based on the secret information without providing the secret information to the secure device processor, receive the non-secret information from the secure element, and generate a second verification for the access based on the non-secret information, where the content and/or application is accessible from the secure download application function responsive to the first and second verifications. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a system that provides a first message to a communication device that includes a temporary international mobile subscriber identity (IMSI) to be provisioned onto the device. A first registration message is sent to a registration function server, wherein the server includes a registry, wherein the first registration message indicates to the server to add the temporary IMSI to the registry. A second registration message is sent to the server in response to detecting expiration of a limited time period, wherein the second registration message indicates to the server to remove the temporary IMSI from the registry. A second message is provided to the wireless communication device that indicates to the wireless communication device the expiration of the limited time period, and that the temporary IMSI is removed from the registry of the registration function server. Other embodiments are disclosed.

Abstract: A system is described that can perform a method for providing a first mobile network operator system with information relating to configuration data. The configuration data enables management of content and memory allocation for security domain containers of a universal integrated circuit card of a communication device. Security management of the universal integrated circuit card is delegated by providing the configuration data to a second mobile network operator system to enable management of the content and the memory allocation for the security domain containers. The memory allocation is adjusted by the second network mobile operator system according to a second group of services provided to the communication device.
