摘要:
An embodiment of the invention provides for an authenticated launch of VMs and nested VMMs. The embodiment may do so using an interface that invokes a VMM protected launch control mechanism for the VMs and nested VMMs. The interface may be architecturally generic. Other embodiments are described herein.

In one embodiment, a security logic of first portable device is configured to receive first motion sample information from at least one motion sensor of the first portable device and second motion sample information from at least one motion sensor of a second portable device, the first and second motion sample information obtained responsive to training movement of the first and second portable devices by a first user. Based on the motion sample information, the security logic is configured to generate a device pairing value, generate a first confidence value based on the first motion sample information and first reference motion sample information stored in the first portable device corresponding to reference movement of the first portable device by the first user, generate a relationship key pair for a relationship, and communicate the first confidence value and a public key of the relationship key pair to the second portable device using the device pairing value. Other embodiments are described and claimed.

An apparatus may include an interface to receive a multiplicity of user information samples at a respective multiplicity of instances; a processor circuit, and an entropy multiplexer for execution on the processor circuit to generate a pseudo random number based upon a pseudo random number seed and pseudo random number algorithm for each user information sample of the multiplicity of user information samples. Other embodiments are described and claimed.

Methods, apparatus, systems and articles of manufacture are disclosed to facilitate multi-factor authentication policy enforcement using one or more policy handlers. An example first policy handler to manage a global policy in a distributed environment includes a parser to identify a first sub-policy of the global policy that is capable of enforcement by the first policy handler, and an attester to sign the first sub-policy. The example first policy handler further includes a director to determine whether to forward the global policy to a second policy handler based on a signature status of the global policy, and to forward the global policy to the second policy handler when the signature status of the global policy is indicative of an unsigned second sub-policy.
摘要:
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.

Generally, this disclosure describes technologies for restoring and/or synchronizing templates such as biometric templates to/among one or more client devices. In some embodiments one or more client devices may register with a synchronization server and provide encrypted copies of their reference templates to the server. In a restoration operation, the synchronization server may provide an encrypted copy of a client's reference template(s) to the client, which may decrypt them in a protected environment. In a synchronization operation, the synchronization server may provide encrypted copy of a first client's template(s) to a plurality of second clients. The second clients may then decrypt the encrypted template(s) within a protected environment using an appropriate decryption key.
摘要:
A manageability engine, and/or operations thereof, for controlling access to one or more resources of a computer device. In an embodiment, the manageability engine executes an authentication agent to perform authentication of a local user of a computer platform which includes the manageability engine. In another embodiment, the manageability engine includes a device driver to control an input/output device for the local user to exchange an authentication factor via a trusted path between the input/output device and the manageability engine.

Described herein are techniques related to a tap-to-wake and tap-to-login system. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope and meaning of the claims. A tap-to-wake and tap-to-login system allows a user of a near field device to wake up a computing platform from a deep sleep state using a bump/tap without having to move a mouse or enter a keyboard stroke.
摘要:
A method and device for securely provisioning trust anchors includes generating a database wrapper key as a function of computing device hardware. The database wrapper key encrypts a key database when it is not in use by a trusted execution environment and may be generated using a Physical Unclonable Function (PUF). A local computing device establishes a secure connection and security protocols with a remote computing device. In establishing the secure connection, the local computing device and remote computing device may exchange and/or authenticate cryptographic keys, including Enhanced Privacy Identification (EPID) keys, and establish a session key and device identifier(s). One or more trust anchors are then provisioned depending on whether unilateral, bilateral, or multilateral trust is established. The local computing device may act as a group or domain controller in establishing multilateral trust. Any of the devices may also require user presence to be verified.

Embodiments of the invention are generally directed to systems, methods, and apparatuses for controlling a network connection based, at least in part, on dual-switching. In an embodiment, a tunnel proxy is coupled with a host execution environment. The tunnel proxy includes logic to provide a security protocol client and logic to provide a security protocol server. In one embodiment, the tunnel proxy provides a proxy for a policy decision point to the host execution environment. Other embodiments are described and claimed.
