    Abstract: A device may receive a request to establish a virtualized environment to support a session for a client device in communication with the computing device over a network. The device may instantiate the virtualized environment in a trusted execution environment of the device, wherein the trusted execution environment may include one or more hardware resources that isolate the virtualized environment from a rich execution environment associated with the device. The device may cause a hardware security module associated with the device to obtain one or more cryptographic keys by communicating with a secure element of the client device, and the device may secure communication between a local operating system executing on the client device and the virtualized environment instantiated in the trusted execution environment using the one or more cryptographic keys.

    Abstract: A device receives, from an application, a request to access an attestation key stored in a secure element of the device. The device obtains an attestation policy, by which to verify an identity of the application. The device examines an application file associated with the application, to determine whether the application file satisfies the attestation policy. The device selectively generates a temporary key based on a result of examining the application file. The temporary key may be used to access the attestation key. The temporary key may be generated based on the application file satisfying the attestation policy, and may not be generated based on the application file not satisfying the attestation policy.

    Abstract: Information regarding the status of an update to a universal integrated circuit card (UICC) being performed across a mobile wireless communication network is provided to a server involved in the update process and/or to a user of the mobile communication device having the UICC. The UICC update server sends an update trigger to the mobile communication device, and the UICC initiates establishment of a communication link to receive the update. The UICC further causes a baseband processor of the mobile communication device to send a proof-of-receipt of the update trigger by short message service (SMS) messaging back to the update server. Additionally or alternatively, the UICC causes the baseband processor to send a wakeup message to a mobile device application executing on the mobile device. The wakeup message includes status information relating to the UICC update which can be provided to a user of the mobile device.

    Abstract translation: 关于通过移动无线通信网络执行的通用集成电路卡(UICC)的更新状态的信息被提供给涉及更新过程的服务器和/或具有UICC的移动通信设备的用户。 UICC更新服务器向移动通信设备发送更新触发器,并且UICC发起建立通信链路以接收更新。 UICC还使得移动通信设备的基带处理器通过短消息服务(SMS)消息发送更新触发的接收证明回到更新服务器。 另外或替代地,UICC使得基带处理器向在移动设备上执行的移动设备应用发送唤醒消息。 唤醒消息包括可以提供给移动设备的用户的与UICC更新有关的状态信息。
