摘要： The present disclosure is directed to an end-to-end secure communication system wherein, in addition to encrypting transmissions between clients, communication-related operations occurring within each client may also be secured. Each client may comprise a secure processing environment to process encrypted communication information received from other clients and locally-captured media information for transmission to other clients. The secure processing environment may include resources to decrypt received encrypted communication information and to process the communication information into media information for presentation by the client. The secure processing environment may also operate in reverse to provide locally recorded audio, image, video, etc. to other clients. Encryption protocols may be employed at various stages of information processing in the client to help ensure that information being transferred between the processing resources cannot be read, copied, altered, etc. In one example implementation, a server may manage interaction between clients, provision encryption keys, etc.

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： 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.

摘要： Technologies for authenticity assurance for I/O data include a computing device with a cryptographic engine and one or more I/O controllers. A metadata producer of the computing device performs an authenticated encryption operation on I/O data to generate encrypted I/O data and an authentication tag. The metadata producer stores the encrypted I/O data in a DMA buffer and the authentication tag in an authentication tag queue. A metadata consumer decrypts the encrypted I/O data from the DMA buffer and determines whether the encrypted I/0 data is authentic using the authentication tag from the authentication tag queue. For input, the metadata producer may be embodied as the cryptographic engine and the metadata consumer may be embodied as a trusted software component. For output, the metadata producer may be embodied as the trusted software component and the metadata consumer may be embodied as the cryptographic engine. Other embodiments are described and claimed.

摘要： Technologies for supporting and implementing multiple digital rights management protocols on a client device are described. In some embodiments, the technologies include a client device having an architectural enclave which may function to identify one of a plurality of digital rights management protocols for protecting digital information to be received from a content provider or a sensor. The architectural enclave select a preexisting secure information processing environment (SIPE) to process said digital information, if a preexisting SIPE supporting the DRM protocol is present on the client. If a preexisting SIPE supporting the DRM protocol is not present on the client, the architectural enclave may general a new SIPE that supports the DRM protocol on the client. Transmission of the digital information may then be directed to the selected preexisting SIPE or the new SIPE, as appropriate.

摘要： The present disclosure is directed to application integrity protection via secure interaction and processing. For example, interaction with a user interface in a device may result in input information being generated. Following encryption, the input information may be conveyed to an application executing in a secure processing environment. The encrypted input information may be received, decrypted and processed by the application. An example application may include a secure controller component, a secure model component and a secure view component. The secure controller component may, for example, provide change instructions to the secure model component based on the decrypted input information. The secure model component may then, if necessary, provide a change notification to the secure view component based on the change instructions. The secure view component may then generate output information, which may be encrypted prior to being provided to the user interface for decryption, processing and presentation.
