摘要： Technologies for cryptographic protection of I/O audio data include a computing device with a cryptographic engine and an audio controller. A trusted software component may request an untrusted audio driver to establish an audio session with the audio controller that is associated with an audio codec. The trusted software component may verify that a stream identifier associated with the audio session received from the audio driver matches a stream identifier received from the codec. The trusted software may program the cryptographic engine with a DMA channel identifier associated with the codec, and the audio controller may assert the channel identifier in each DMA transaction associated with the audio session. The cryptographic engine cryptographically protects audio data associated with the audio session. The audio controller may lock the controller topology after establishing the audio session, to prevent re-routing of audio during a trusted audio session. Other embodiments are described and claimed.

摘要： According to some embodiments, an apparatus may be capable of exchanging information with t potential universal serial bus endpoints, where t is an integer greater than 1. Moreover, x endpoint state machines may be established, where x is an integer greater than 1 and less than t. A first endpoint state machine may then be assigned to a first potential endpoint having a pending work item. Before the apparatus has completed the pending work item associated with the first potential endpoint, the first endpoint state machine may be flushed, and the first endpoint state machine may be re-assigned to a second potential endpoint.

摘要： Channel multiplexing and flow control may be incorporated in wireless communications, especially in short-range wireless communication systems. In one embodiment, a wireless communication system may include a source and a target transceiver to communicate data over a wireless communication link, such as a radio link. At the source transceiver, a first payload of data may be broken into one or more first fragments to control multiplexing of the one or more first fragments. To communicate the first payload, each first fragment may be labeled as at least one of a beginning and an ending fragment. Likewise, a second payload of data may be broken into one or more second fragments. Each second fragment may be identified as at least one of a start, intermediate, end or a single fragment. Each of the first and second fragments may be sized to control latency. While the first payload of data may be provided on a first channel, the second payload of data may be provided on a second channel. By advantageously arbitrating transmission of the first and second fragments, the first and second channels may be multiplexed at a fragment granularity rather than at a payload granularity, providing finer control of payload latency and a more robust short-range wireless communication link.
摘要翻译：信道复用和流控制可以并入无线通信，特别是在短距离无线通信系统中。在一个实施例中，无线通信系统可以包括源和目标收发器，以通过诸如无线电链路的无线通信链路传送数据。在源收发器处，数据的第一有效载荷可以被分解为一个或多个第一片段以控制一个或多个第一片段的复用。为了传送第一有效载荷，每个第一片段可以标记为开始和结束片段中的至少一个片段。类似地，数据的第二有效载荷可以被分解成一个或多个第二片段。每个第二片段可以被鉴定为起始，中间，末端或单个片段中的至少一个片段。第一和第二片段中的每一个可以被设置成控制等待时间。虽然可以在第一信道上提供数据的第一有效载荷，但是可以在第二信道上提供数据的第二有效载荷。通过有利地仲裁第一和第二片段的传输，可以以片段粒度而不是有效载荷粒度来复用第一和第二信道，从而提供更有效的控制有效载荷延迟和更强壮的短距离无线通信链路。

摘要： Using a non-coherent optical bundle having a plurality of fibers for image transmission. The fibers of the non-coherent optical bundle may be calibrated to generate a mapping function. Image data at a sending end of the non-coherent optical bundle may be obtained and transmitted over the non-coherent optical bundle, the image data being scrambled during transmission to produce scrambled image data at a receiving end of the non-coherent optical bundle. The mapping function may be applied to the scrambled image data to reproduce the image data for use in an imaging system.

摘要： Technologies for secure programming of a cryptographic engine include a computing device with a cryptographic engine and one or more I/O controllers. The computing device establishes, an invoking secure enclave using secure enclave support of a processor. The invoking enclave configures channel programming information, including a channel key, and invokes a processor instruction with the channel programming information as a parameter. The processor generates wrapped programming information including an encrypted channel key and a message authentication code. The encrypted channel key is protected with a key known only to the processor. The invoking enclave provides the wrapped programming information to untrusted software, which invokes a processor instruction with the wrapped programming information as a parameter. The processor unwraps and verifies the wrapped programming information and then programs the cryptographic engine. The processor generates an authenticated response that may be verified by the invoking enclave. Other embodiments are described and claimed.
