Abstract: Two unmanned vehicles come within communication range of one another. The unmanned vehicles exchange logs of messages each has received. Each of the unmanned vehicles analyzes the messages that it received from the other unmanned vehicle to determine whether any of the received messages warrants changing a set of tasks it was planning to perform. When a message indicates that a task should be changed, the task is updated accordingly.

Abstract: A method of implementing a network-enabled secure door lock, comprising determining, at a first component of the lock, a nonce; wirelessly transmitting the nonce to a second component of the door lock, the first component and second component selectively mechanically engagable with one another to prevent relative movement between the first component and second component to prevent opening of a door; receiving, at the first component, a first message; using a cryptographic key associated with the second component and the nonce to validate the first message; and as a result of determining that the message is valid, transmitting a second message indicating that the first component and second component have become mechanically engaged with one another.

Abstract: Disclosed are various embodiments for malware detection by way of proxy servers. In one embodiment, a proxied request for a network resource from a network site is received from a client device by a proxy server application. The proxied request is analyzed to determine whether the proxied request includes protected information transmitted in an unsecured manner. It is then determined whether the network resource comprises malware based at least in part on an execution of the network resource or whether the proxied request includes the protected information transmitted in the unsecured manner. The proxy server application refrains from sending data generated by the network resource to the client device in response to the proxied request when the network resource is determined to comprise the malware.

Abstract: A system and method for a quarantine network for a personal rea network are provided. A plurality of devices that are connected to a first personal area network are identified. A first device is designated as being authorized to communicate using the first personal area network and a second device of the plurality of devices is designated as not being authorized to communicate using the first personal area network. The first device is instructed to disconnect from the first personal area network. Communications with the second device are ceased. After ceasing communication with the second device, the second device continues to be connected to the first personal area network. It is then determined that the first device is connected to a second personal area network. The first device is instructed the first device to use a network key for communications with a network controller.

Abstract: A device provisioning service (DPS) fields requests from unprovisioned devices so that those unprovisioned devices can obtain network credentials or other data used in provisioning the unprovisioned device. The DPS can identify the device securely and associate with a known user account, or the user provisioning the device can supply network credentials over a side channel after supplying a provision code indicative of possession of the unprovisioned device. The provision code can be unique to the unprovisioned device or a short-sequence code that is not necessarily unique, but that is sufficiently uncommon that a specific short-sequence code would not likely be used more than once at a time. In order to communicate with the DPS, a provisioning device might connect the unprovisioned device and the DPS. If the provisioning device is a trusted device, it can perform some of the steps otherwise required by the DPS.

Abstract: In some cases, a provisioned electronic device may receive a request for configuration information from an unprovisioned device. In response, the provisioned device may determine configuration information to send to the unprovisioned device based at least in part on the contents of the request. Examples of configuration information may include network credentials for connecting to a wireless local area network, a registration token that identifies the unprovisioned device to a fulfillment service, and user preferences associated with a user of the provisioned device. Further, the provisioned device may send the configuration information to the unprovisioned device. Upon receipt of the configuration information, the unprovisioned device may utilize the configuration information to order products from the fulfillment service. In some instances, the provisioned device may obtain the configuration information from the fulfillment service.

Abstract: Features are disclosed for a security camera including automated identification of disabled privacy indicators based on feedback included in monitored data (e.g., images). The features include generating a random number and adjusting light emitted by the privacy indicator to signal the random number. The camera may detect subtle changes (e.g., brightness, color, hue, intensity) in the image, a sequence of images, or portions thereof that can be decoded and compared to the random number. If there is a discrepancy between the random number and decoded value, an indication of tampering with the privacy indicator may be provided.

Abstract: Computing devices are disclosed that include functionality for providing a trustworthy indication of software integrity. The computing devices include a hardware trust evaluation device capable of determining the trustworthiness of computer programs executing on the devices. At least one trust indicator is also connected to the hardware trust evaluation device for providing an external indication of the trustworthiness of a computer program. Additional security information regarding the trustworthiness of the computer program may be displayed on the primary display device of the computing device. The display of the security information is triggered by a user of the computing device submitting a request through a secure mechanism, where the request is unobservable and inaccessible to programs executing on the computing device. Additional secure mechanisms, such as a unique user interface for displaying the security information, can be utilized to ensure the authenticity of the displayed security information.

Abstract: An access control application for mobile devices is provided.

The user's response to the security tasks may be obtained and a confidence score may be calculated, based at least in part on the response. The access control application may then determine, based at least in part on the score and one or more attributes of the environment, whether to unlock the mobile device or prompt the user to provide an additional response to another security task.
