    Abstract: A destination data processing system (DPS) receives a key migration block from a source DPS. The key migration block includes an encrypted version of a primary key. The destination DPS receives user input that identifies (a) an authentication policy and (b) a context policy. The destination DPS collects authentication data from the user, based on the identified authentication policy. The destination DPS collects context data, based on the identified context policy. The destination DPS uses the authentication data and the context data to decrypt the key migration block. The authentication data may comprise multiple types of authentication data, possibly including biometric data. The user may also input an index, and the destination DPS may use the index to retrieve a number from a random number server. The destination DPS may use that number to decrypt the key migration block. Other embodiments are described and claimed.

    Abstract: Technologies for de-duplicating encrypted content include fragmenting a file into blocks on a computing device, encrypting each block, and storing each encrypted block on a content data server with associated keyed hashes and member identifications. The computing device additionally transmits each encrypted block with an associated member encryption key and member identification to a key server. As part of the de-duplication process, the content data server stores only one copy of the encrypted data for a particular associated keyed hash, and the key server similarly associates a single member encryption key with the keyed hash. To retrieve the file, the computing device receives the encrypted blocks with their associated keyed hashes and member identifications from the content data server and receives the corresponding member decryption key from the key server. The computing device decrypts each block using the member decryption keys and combines to blocks to generate the file.

    Abstract: In one embodiment, a binary translator to perform binary translation of code is to: perform a first binary analysis of a first code block to determine whether a second control transfer instruction is included in the first code block, where the first code block includes a return target of a first control transfer instruction; perform a second binary analysis of a second code block to determine whether the second code block includes the first control transfer instruction, where the second code block includes a call target of the second control transfer instruction; and store an address pair associated with the first control transfer instruction in a whitelist if the second control transfer instruction is included in the first code block and the first control transfer instruction is included in the second code block. Other embodiments are described and claimed.

    Abstract: Measurement exchange networks and protocols to exchange measurements of a parameter amongst devices (e.g., IoT devices), select the best measurement(s), accuracy/precision-wise, and determine a process variable for a control system based on the selected best measurement(s). A device may select a peer-provided best measurement to output as the process variable in place of a local measurement, and/or compute the process variable from multiple best measurements (e.g., local and/or peer-provided measurements). Metadata may be used to select a measurement(s) and/or to increase reliability/trust of exchanged data. In this way, each device of an exchange group/network may obtain the highest measurement accuracy of all available collocated sensors with little or no additional processing or cloud connectivity. A best measurement(s) may be selected based on measurement quality specifications extracted from metadata, measurement qualities computed from measurements of respective sensors, locations/proximities of the sensors, a policy(ies), and/or device IDs (e.g., extracted from metadata).

    Abstract: A circuit includes a first communication interface configured to receive first sensor data from a stationary sensor. The first sensor data include a result of a first sensing of a local environment of the stationary sensor performed by the stationary sensor. The circuit may further include a second communication interface configured to receive second sensor data from an unmanned aerial vehicle. The second sensor data include a result of a second sensing of at least a portion of the local environment of the stationary sensor performed by a sensor of the unmanned aerial vehicle. The circuit may further include one or a plurality of processors configured to compare the first sensor data and the second sensor data and to classify the at least one stationary sensor based on a result of the comparison.
