    摘要： Provisioning a license and an application program from a first server to a computing platform over a network. The host application derives a symmetric key at least in part from a user password, and sends the license to a license management firmware component of a security engine, in a message signed by the symmetric key. The license management firmware component derives the symmetric key at least in part from the user password stored in a secure storage of the security engine, verifies the signature on the message using the symmetric key, verifies the first server's signature on the license, decrypts the license using a first private key of the license management firmware component corresponding to the first public key to obtain the second key, and sends the second key to the host application, which decrypts the application program using the second key.

    摘要： A method, apparatus, system, and computer program product for a secure subscriber identity module service. Communication via a mobile network is activated in response to receiving a request to activate communication service for the system by a secure partition of the system. In response to receiving the request, a key is retrieved for a permit service from storage accessible only by the secure partition. The key is included in a permit requesting to activate the communication service, and the permit is sent to a service provider for the communication service. The service provider communicates with the permit service to obtain a digital signature for the permit. The secure partition receives a signed permit from the service provider, confirms that the signed permit contains the digital signature by the permit service, and activates the communication service for the system in response to confirming that the signed permit contains the digital signature.

    摘要： A method to lock an electronic device comprising an operating system comprises placing the electronic device in a disable state in which the processor is blocked from accessing the operating system, receiving a first unlock password from a remote source during a power-up operation of the electronic device, and placing the electronic device in a temporary unlock state which allows the processor to boot the operating system for a predetermined period of time when the first unlock password matches a password stored in the electronic device. Other embodiments may be described.

    摘要： A method of communicating a payment request from a first payment platform to a second payment platform is disclosed. The method may receive a payment request from a sending user on the first payment platform to a receiving user on the second payment platform where the payment request from the sending user is translated into a protected payment request. In response to the sending user being known, the protected payment request may be communicated to the second payment platform. An acceptance of the protected payment request from the second payment platform may be received. A transaction settlement request may be communicated to the first payment platform and the second payment platform.

    摘要： A method and system for cycle accurate data transfer between skewed source synchronous clocks is envisaged. The procedure starts through reset. On reset, both the write and read address registers are set to point to location 0. Source clock is stopped to disable active clock edges to both write and read address registers during the reset procedure. The source clock is subsequently started to deliver active edges w both write and read address registers. On every active source clock edge, data is pushed into the data register based on the location pointed by write address resister. On every skewed active clock edge, data is read from the data register based on the address pointed by read address register. Due to the delayed nature of clock reaching the read address register, write address register increments first and stores data into the data register.
