Technologies for trusted device on-boarding include a first computing device to generate a first public Diffie-Hellman key based on a private Diffie-Hellman key and a first unique identifier of the first computing device. The first unique identifier is retrieved from secure memory of the first computing device. The first computing device transmits the first public Diffie-Hellman key to a second computing device and receives, from the second computing device, a second public Diffie-Hellman key of the second computing device. The second public Diffie-Hellman key incorporates a second unique identifier of the second computing device. Further, the first computing device removes a contribution of the second unique identifier from the second public Diffie-Hellman key to generate a modified public Diffie-Hellman key and generates a shared Diffie-Hellman key based on the modified public Diffie-Hellman key and the private Diffie-Hellman key of the first computing device.
摘要:
Technologies for genomic data management include a patient device that computes an integrity register value as a function of genomic sequence data within a trusted execution environment. The genomic sequence data may not feasibly be reconstructed from the integrity register value. A genomic server computes an integrity register index of public genomic sequence data. The patient device transmits an integrity register value to the genomic server, and the genomic server responds with population data indicative of the genomic sequence data corresponding to the integrity register value. The patient device may contribute the genomic sequence data to the public genomic sequence data if the population data is sufficiently large. The patient device may also transmit the integrity register value to a research device, and the research device may respond with a compensation offer for the genomic sequence data if the population data is sufficiently small. Other embodiments are described and claimed.
摘要:
According to some embodiments, a method and apparatus are provided to receive a first signal from a sensor, determine that a user is present based on the received first signal, receive a second signal from the sensor, and determine if the user is still present based on the received second signal.
摘要:
A protocol provides authentication of peripheral devices by a computing device to which the peripheral device connects. Computing devices include a verifier with a public key that authenticates multiple associated private keys. Private keys are embedded on peripheral devices. When the verifier is able to authenticate a connected peripheral, particular functionality is enabled that may not be enabled for peripherals that do not authenticate.
摘要:
A mechanism is described for facilitating context-based access control of resources for according to one embodiment. A method of embodiments, as described herein, includes receiving a first request to access a resource of a plurality of resources. The first request may be associated with one or more contexts corresponding to a user placing the first request at a computing device. The method may further include evaluating the one or more contexts. The evaluation of the one or more contexts may include matching the one or more contexts with one or more access policies associated with the requested resource. The method may further include accepting the first request if the one or more contexts satisfy at least one of the access policies.
摘要:
A manageability engine (ME) receives an authentication response from a user during pre-boot authentication and registers the user with a key distribution center (KDC), indicating that the user has successfully authenticated to the PC. The KDC supplies the ME with single-sign-on credentials in the form of a Key Encryption Key (KEK). The KEK may later be used by the PC to obtain a credential used to establish secure access to Enterprise servers.
摘要:
In an embodiment, the present invention includes a method for receiving a request for user authentication of a system, displaying an authentication image on a display of the system using a set of random coordinates, receiving a plurality of gesture input values from the user, and determining whether to authenticate the user based at least in part on the plurality of gesture input values. Other embodiments are described and claimed.
摘要:
Generally, this disclosure describes a continuous authentication confidence module. A system may include user device including processor circuitry configured to determine presence data; a confidence factor including at least one of a sensor configured to capture sensor input and a system monitoring module configured to monitor activity of the user device; memory configured to store a confidence score and an operating system; and a continuous authentication confidence module configured to determine the confidence score in response to an initial authentication of a specific user, update the confidence score based, at least in part, an expectation of user presence and/or selected presence data, and notify the operating system that the authentication is no longer valid if the updated confidence score is within a tolerance of a session close threshold; the initial authentication configured to open a session, the confidence score configured to indicate a current strength of authentication during the session.
摘要:
A method includes generating a chain of trust for a virtual endpoint. The virtual endpoint is associated with a layered architecture that includes layers, which include a physical layer. For each layer, a code image of a process of the layer is measured before the process is loaded to form a node of the chain of trust.
摘要:
Embodiments of the present disclosure are directed towards selective disclosure of user or computing environment attributes to facilitate generation and/or provision of targeted content. In various embodiments, a likelihood that disclosure of an attribute of a user or of a computing environment associated with the user will enable identification of the user may be determined based on an associated population count of users or computing environments sharing the same attribute. In various embodiments, the attribute may be selectively disclosed to a content provider configured to provide targeted content, or a recommendation may be selectively provided to the user as to whether the user should disclose the attribute to the content provider, based on the determination and a risk tolerance associated with the user. In various embodiments, a dimension authority may track and make available population counts of users or computing environments having various attributes.
