  • Patent number: 10404692
    Abstract: Technologies are provided in embodiments to establish trust between a trusted execution environment (TEE) and a peripheral device. Embodiments are configured to communicate with an attestation server to generate an encryption key, and to establish, using the encryption key, a secure connection with an authentication server to enable communication between the authentication server and the peripheral device. Embodiments are also configured to receive a pairwise master key if the peripheral device is authenticated and to receive a trusted communication from the peripheral device based, at least in part, on the pairwise master key. Embodiments may also be configured to identify a connection to the peripheral device before the peripheral device is authenticated to the authentication server, receive an identifier from the peripheral device, and establish a connection to an attestation server based on at least a portion of the identifier.

  • Patent number: 10397112
    Abstract: Technologies for communicating with local components of a computing device include intercepting a name resolution request from a host application, resolving a hostname included in the name resolution request to obtain a network address assigned to a target destination of the network packet, and transmitting the network address to the host application in response to the name resolution request. Such technologies may also include receiving the network packet from the host application destined for the network address, determining whether the target destination of the network packet includes a local component of the computing device based on the network address, and transmitting the network packet to the local component of the computing device via a platform network in response to the network packet being destined for the local component of the computing device.

  • Patent number: 9948468
    Abstract: In an example, a DHN (DHN) is provided for enabling grantees to access digitally-controlled assets of a principal. The principal (level 0) establishes a digital testament (DT), identifying one or more grantees on levels 1-n. Each grantee receives a digital heritage certificate (DHC), which may be based on the PKI certificate definition. The DHC includes a “PREDECESSORS” field, identifying one or more predecessor certificates that must be revoked before the DHC is valid. All grantee DHCs have the principal's level 0, DHC as a predecessor certificate. Level n certificates may also be valid only if all certificates at level n?1, have been revoked. In practice, a DHC may be revoked when a user of the certificate passes away, so that nth generation grantees inherit only when generation n?1, has passed away.

  • Patent number: 9798895
    Abstract: In an example, a client-server platform identity architecture is disclosed. The platform identity architecture may be used to enable a venue operator to provide online services and to collect telemetry data and metrics while giving end users greater control over privacy. When entering a compatible venue, the user's device generates a signed temporary pseudonymous identity (TPI) in secure hardware or software. Any telemetry uploaded to the venue server includes the signature so that the server can verify that the data are valid. The TPI may have a built-in expiry. The venue server may thus receive useful tracking data during the term of the TPI, while the user is assured that the data are not kept permanently or correlated to personally-identifying information.
