  • Publication number: 20200014974
    Abstract: In some aspects, the disclosure is directed to methods and systems for controlling a set top box remotely and monitoring its display output. Remote control commands may be intercepted or captured and forwarded over a network as encapsulated serial data or HDMI-CEC, in some implementations. This data may be transmitted over a network to a processing device, sometimes referred to as an HDMI pass-through and streamer device. The HDMI pass-through device may receive the encapsulated serial data via the network and retransmit the data as CEC data over HDMI to the set top box as if it were any other HDMI capable device, such as a television. Thus, the recipient set top box may receive the remote control commands via CEC and treat them as incoming IR commands and act accordingly.

  • Publication number: 20190327092
    Abstract: In some aspects, the disclosure is directed to methods and systems for using biometric authentication on local or remote devices, without requiring a secure communication channel between the devices. An enrollment operation may be performed on a first device. The enrollment data and user credentials may be encrypted using a cryptography key generated using the biometric information. The encrypted enrollment data may be transferred to the remote device via any available communication channel regardless of its security. On the remote device, the cryptographic key may be regenerated using newly captured biometric data, and the enrollment data and user credentials decrypted. This allows the user to completely eliminate the use of passwords and re-enrollment of biometric authentication on the remote device.

  • Publication number: 20190289038
    Abstract: In some aspects, the disclosure is directed to methods and systems for providing coordinative security among network devices across multi-level networks. Shared cryptographic secrets among the network devices are used as the basis for mutual security authentication and peering among these devices. The cryptographic secrets can be embedded in the SoC devices for these devices or dynamically generated based on unique identification information and attributes of these SoC devices. The messages for authentication and peering can be communicated directly among the network devices or indirectly via a cloud security portal entity that acts as a messaging proxy. The mutual authentication and peering process can be carried out coordinately among the network devices and a cloud security portal in a one-to-one mesh relationship, or in a transitive layering relationship, where each network entity authenticates and peers with its direct subordinates in a multi-level network.

  • Publication number: 20190278886
    Abstract: A system and method are disclosed for provisioning IP features in a system-on-chip. A plurality of identical chips are fabricated, each of which is capable of have a number of features enabled or disabled. As a default, all features are disabled. A production process is later carried out, in which the chip is installed in a greater device. During this process, the manufacturer requests a license the IP owner for enablement of various features. Using secure communications, a license is granted identifying the features to be enabled, and a volume of units permitted to be manufactured. The license information is encrypted using a key already known to the chip, and sent to the manufacturer. The chip receives the license information during provisioning, extracts relevant provisioning information using the key, and a secure processing system provisions the relevant features. Log information is generated to allow the IP owner to verify license compliance.

  • Publication number: 20190089520
    Abstract: In some aspects, the disclosure is directed to methods and systems for controlling periodic jitter arising from a phase interpolator (PI). A receiver can receive incoming data. A fractional-N phase-locked loop (PLL) can receive a reference clock. Measurement circuitry can measure a parts per million (PPM) offset between the incoming data and the reference clock, of a PI. The fractional-N PLL can restrict jitter arising from the PI, to frequencies within a predefined bandwidth, by tuning a center frequency of the fractional-N PLL to reduce the PPM offset of the PI.
