Abstract:
The present disclosure is directed to secure vehicular data management with enhanced privacy. A vehicle may comprise at least a vehicular control architecture (VCA) for controlling operation of the vehicle and a device. The VCA may record operational data identifying at least one vehicle operator and vehicular operational data recorded during operation of the vehicle by the at least one vehicle operator. The device may include at least a communication module and a trusted execution environment (TEE) including a privacy enforcement module (PEM). The PEM may receive the operational data from the VCA via the communication module, may generate filtered data by filtering the operational data based on privacy settings and may cause the filtered data to be transmitted via the communication module. The filtered data may be transmitted to at least one data consumer. The privacy settings may be configured in the PEM by the at least one operator.
Abstract:
Embodiments of the present disclosure are directed toward publication and/or removal of attributes in a multi-user computing environment. In some embodiments, a consumer information manager (CIM) associated with a user of a multi-user computing system may receive a notification, from a dimension authority (DA), of a decrease in a population count of users of the computing system who have published an attribute within the computing system, and may determine whether the user has published the attribute. In response to receiving the notification of the decrease and determining that the user has published the attribute, the CIM may determine a likelihood that continued publication of the attribute will enable identification of the user, compare the likelihood to a threshold, and, when the likelihood exceeds the threshold, remove the attribute from publication. Other embodiments may be disclosed and/or claimed.
Abstract:
Technologies for utilizing trusted messaging include a local computing device including a message client and a local trusted message module established in a trusted execution environment. The local trusted message module performs attestation of a remote computing device based on communication with a corresponding remote trusted message module established in a trusted execution environment of the remote computing device. The local trusted message module further exchanges, with the remote trusted message module, cryptographic keys in response to successful attestation of the remote computing device. The message client forwards outgoing messages to the local trusted message module and receives incoming messages from the local trusted message module. To securely transmit an outgoing message to the remote computing device, the local trusted message module receives the outgoing message from the message client, encrypts the outgoing message, and cryptographically signs the outgoing message, prior to transmittal to the remote trusted message module of the remote computing device. To securely receive an incoming message from the remote computing device, the local trusted message module receives the incoming message from the remote trusted message module of the remote computing device, decrypts the incoming message, and verifies a cryptographic signature of the incoming message, based on the exchanged cryptographic keys and prior to transmittal of the incoming message to the message client.
Abstract:
In one embodiment, a method includes: presenting, in a user interface of an authoring tool, a plurality of levels of abstraction for a network having a plurality of devices; receiving information from a user regarding a subset of the plurality of devices to be provisioned with one or more security keys and an access control policy; automatically provisioning a key schedule for the subset of the plurality of devices in the network based on the user input and a topological context of the network; and automatically provisioning the access control policy for the subset of the plurality of devices in the network based on the user input and the topological context of the network.
Abstract:
A data processing system (DPS) supports exchange of digital keys. The DPS comprises a communication module which, when executed by the DPS, is operable to receive, via multiple different network routes, multiple copies of a seed message from a second DPS, as part of a Diffie-Hellman key exchange process with the second DPS, wherein each copy of the seed message includes a seed value. The DPS also comprises a security module which, when executed by the DPS, is operable to perform operations comprising (a) determining a prevalent seed value, based on the multiple copies of the seed message; (b) computing a prevalence metric to indicate how many of the seed messages contained the prevalent seed value; and (c) determining whether a seed exchange portion of the Diffie-Hellman key exchange process has been successfully performed, based on the prevalence metric. Other embodiments are described and claimed.

Abstract:
Generally, this disclosure describes a system including a privacy aware DHCP service and a user device. The user device includes a trusted execution environment including a client privacy agent configured to request a first Internet Protocol (IP) address from a DHCP service and to determine a device privacy score based, at least in part, on a DHCP policy; memory comprising secure storage configured to store the first IP address; and communication circuitry configured to establish at least one connection between the user device and at least one entity over a network using the first IP address. The client privacy agent is configured to monitor communication activity over the connection(s), to update the device privacy score based, at least in part, on the communication activity, and to close the connection(s) if the device privacy score is outside an acceptable privacy score range, the acceptable privacy range bounded by a privacy threshold.
Abstract:
This disclosure is directed to privacy enforcement via localized personalization. An example device may comprise at least a user interface to present content. A message may be received into a trusted execution environment (TEE) situated within the device or remotely, the message including at least metadata and content. The TEE may determine relevance of the content to a user based on the metadata and user data. Based on the relevance, the TEE may cause the content to be presented to the user via the user interface. In one embodiment, the TEE may be able to personalize the content based on the user data prior to presentation. If the content includes an offer, the TEE may also be able to present counteroffers to the user based on user interaction with the content. The TEE may also be able to cause feedback data to be transmitted to at least the content provider.

Abstract:
Techniques and mechanisms to provide indemnification for a transaction involving communications between networked devices. In an embodiment, attestation logic of a first device sends to a second device attestation information to indicate a trustworthiness level of first device. Based on the attestation information, indemnification logic of the second device determines an indemnification value representing a cost of an indemnification for a first transaction. Indemnification logic of the first device receives the indemnification value and determines, based on the indemnification value, whether a participation in the transaction is to take place.
