    摘要： Systems, methods, and devices for processing video data are disclosed. Some examples include a content receiver including an unsecure processor and an unsecure memory coupled to the unsecure processor. The example includes content protection zone hardware including a secure memory and an input for receiving content. The input coupled to the content protection zone hardware, wherein the content protection zone hardware determines if the received content is secure or unsecure and directs secure content to the secure memory and unsecure content to the unsecure memory.

    摘要： This disclosure provides systems, methods, and devices for wireless communication that support improved routing of image sensors that share a PHY within different secure domains. In a first aspect, a device may receive a packet from an image sensor along a physical data connection. The device may determine a virtual channel associated with the packet and may determining a secure domain for the packet based on the virtual channel. The first secure domain may be selected from a plurality of secure domains accessible via the physical data connection, such as based on a mapping maintained by the device. The device may then route the packet within the first secure domain such that further processing and storage of the packet occurs within the first secure domain, such as within a context base associated with the first secure domain. Other aspects and features are also claimed and described.

    摘要： Security techniques for a Peripheral Component Interconnect (PCI) express (PCIE) system include a transport layer protocol (TLP) packet that has a prepended TLP prefix indicating the security features of the TLP packet and an integrity check value (ICV) appended to the TLP packet. The ICV is based on the TLP packet and any TLP prefixes including a security prefix. At a receiver, if the ICV does not match, then the receiver has evidence that the TLP packet may have been subjected to tampering. Further, the TLP packet may be encrypted to prevent snooping, and this feature would be indicated in the TLP prefix. Still further, the TLP prefix may include a counter that may be used to prevent replay attacks. PCIE contemplates flexible TLP prefixes, and thus, the standard readily accommodates the addition of a TLP prefix which indicates the security features of the TLP packet.

    摘要： Systems, methods, devices, and non-transitory media of the various embodiments facilitate real time playback of a digital broadcast by enabling reduction of the amount of time a receiver device's low power mode interface with a separate computing device operates in an operational/high power mode. The receiver device may associate a stream of media packets of a digital broadcast with system time clock timestamps indicating when the media packets were received, and store the media packets in a temporary packet buffer. Periodically, a media packet burst stored in the temporary packet buffer may be sent to the separate computing device via a low power mode interface operating in an operational/high-power mode different than a low power mode. The low power mode interface may be returned to the low-power mode until the next burst of packets is sent to the separate computing device.
