  • Publication number: 20150121487
    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.

  • Publication number: 20150113617
    Abstract: A system that incorporates the subject disclosure may perform, for example, receiving a baseline credential and an external credential, mapping the external credential to the baseline credential in a secure element memory, receiving a request for an authentication from a secure device processor of the communication device where the request for the authentication includes a user credential inputted into the communication device, comparing the user credential with the baseline credential to verify the authentication, and providing the authentication and the external credential to the secure device processor without providing the baseline credential to enable the secure device processor to provide the external credential to an external entity device that is remote from the communication device. Other embodiments are disclosed.

  • Publication number: 20150100788
    Abstract: A system that incorporates the subject disclosure may perform, for example, operations including receiving an encrypted secure token from a secure token application function that is remote from the communication device, storing the encrypted secure token in a secure element memory of the secure element, accessing user input requesting the encrypted secure token where the secure device processor is separate from the secure element and is in communication with the secure element, generating a modified secure token by adding identification information to the encrypted secure token and by performing a second encryption of the encrypted secure token with the identification information, receiving the modified secure token from the secure element, and providing the modified secure token to a receiving device. Other embodiments are disclosed.

  • Publication number: 20150089225
    Abstract: A system that incorporates the subject disclosure may include, for example, a system for receiving a request to modify a universal integrated circuit card, generating a package comprising configuration data for modifying the universal integrated circuit card, encrypting the package with a transport key to generate an encrypted package, transmitting the encrypted package to a communication device communicatively coupled to the universal integrated circuit card to provision the universal integrated circuit card, and providing a mobile network operator trusted service manager system information relating to the configuration data to enable the mobile network operator trusted service manager system to manage content and memory allocation of the universal integrated circuit card. Other embodiments are disclosed.

  • Publication number: 20150071437
    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.

  • Publication number: 20150044995
    Abstract: A system is described that can perform a method for receiving a request to modify a universal integrated circuit card, generating a package comprising configuration data for modifying the universal integrated circuit card, instructing an over-the-air system to transmit the package encrypting the package with a transport key to generate an encrypted package, and transmitting the encrypted package to a communication device communicatively coupled to the universal integrated circuit card to provision the universal integrated circuit card. The system can also perform a method of providing a mobile network operator trusted service manager system information relating to the configuration data to enable the mobile network operator trusted service manager system to manage content and memory allocation of the universal integrated circuit card.

  • Patent number: 7873317
    Abstract: A wireless communication system includes a wireless peripheral device, a computer device, and a wireless interface capable of communicating with the peripheral device and the computer device. The wireless interface is configured to receive a communication directed to the wireless peripheral device from the computer, transmit wireless signals using a plurality of wireless technology standards at the same time to the wireless peripheral device, and receive an acknowledgement message from the wireless peripheral device. The acknowledgement message identifies at least one wireless technology standard utilized by the wireless peripheral device.

  • Patent number: 7587169
    Abstract: Methods and apparatuses are disclosed for communicating with wireless peripheral devices. One method receives a communication for the wireless peripheral device. Wireless signals, such as activation, initialization, or registration signals/messages, are communicated to the wireless peripheral device utilizing more than one wireless technology standard. When the wireless peripheral device responds, the communication is forwarded to the wireless peripheral device using a single wireless technology standard.
