In this solution, a two-dimensional filter includes a two-dimensional matrix, where the two-dimensional matrix may be linked to multiple key value element groups, and therefore flexibility of the filter is improved. Further, when it is queried whether a key value element is a key value element included in multiple key value element groups, it only needs to perform a query based on the two-dimensional filter, and it does not need to generate a Bloom filter corresponding to each key value element group. In addition, when it is queried whether a key value element is a key value element included in multiple key value element groups, it does not need to perform queries one by one based on each of multiple Bloom filters. Therefore, a problem of low query efficiency currently is further resolved. | 2017-06-15 |
20170170969 | SYSTEMS, METHODS, SOFTWARE, AND COMPONENTS USING TAMPER-PROOF REAL-TIME CLOCK - The write-access control line for an RTC is combined with a clear line for an RTC signature register, so that changes to the RTC will cause subsequent reads to return an invalidity flag. | 2017-06-15 |
20170170970 | SYSTEMS AND METHODS FOR SECURELY PROVISIONING THE GEOGRAPHIC LOCATION OF PHYSICAL INFRASTRUCTURE ELEMENTS IN CLOUD COMPUTING ENVIRONMENTS - Systems and methods relating to improved security in cloud computing environments are disclosed. According to one illustrative implementation, a method for provisioning physical geographic location of a physical infrastructure device associated with a hypervisor host is provided. Further, the method may include performing processing to obtain initial geo location data of the device, determining verified geo location data of the device by performing validation, via an attestation service component, of the initial geo location data to provide verified geo location data, and writing the verified geo location data into HSM or TPM space of the hypervisor host. | 2017-06-15 |
20170170971 | EXTENDING SHROUDING CAPABILITY OF HOSTING SYSTEM - Technical solutions are described for extending shrouding capability of a virtual server hosting system. An example method includes receiving a request to deploy a shrouded virtual server using a predetermined set of hardware components, and using a shrouded mode. The method also includes adding a guest server to the hosting system, the guest server including the predetermined set of hardware components. The method also includes deploying a preconfigured hypervisor on the guest server, where the preconfigured hypervisor is deployed in an immutable mode that disables changes to security settings of the preconfigured hypervisor. The method also includes deploying, by the preconfigured hypervisor, a preconfigured boot image as an instance of the virtual server on the preconfigured hypervisor. The method also includes sending an identifier of the virtual server for receipt by the client device. | 2017-06-15 |
20170170972 | UNMANNED AERIAL VEHICLE OPERATOR IDENTITY AUTHENTICATION SYSTEM - An unmanned aerial vehicle operator identity authentication system is provided, including a flight control module and a license certificate module connected with each other. The flight control module includes a first encryption and decryption unit for generating a random number code, and a first storage unit for storing a license register table. The license certificate module includes a second storage unit for storing a license certificate identifier, and a second encryption and decryption unit for encrypting the received random number code and the license certificate identifier, and transmitting the encrypted data to the first encryption and decryption unit. After decryption, if the first encryption and decryption unit determines that the decrypted random number code is the same as the original random number code, and the decrypted license certificate identifier exists in the license register table, the operator identity authentication is completed and the UAV can be actuated. | 2017-06-15 |
20170170973 | Uniquely identifying and securely communicating with an appliance in an uncontrolled network - A service consumer that utilizes a cloud-based access service provided by a service provider has associated therewith a network that is not capable of being controlled by the service provider. An enterprise connector is supported in this uncontrolled network, preferably as an appliance-based solution. According to this disclosure, the enterprise configures an appliance and then deploys it in the uncontrolled network. To this end, an appliance is required to proceed through a multi-stage approval protocol before it is accepted as a “connector” and is thus enabled for secure communication with the service provider. The multiple stages include a “first contact” (back to the service) stage, an undergoing approval stage, a re-generating identity material stage, and a final approved and configured stage. Unless the appliance passes through these stages, the appliance is not permitted to interact with the service as a connector. As an additional aspect, the service provides various protections for addressing scenarios wherein entities masquerade as approved appliances. | 2017-06-15 |
20170170974 | METHOD FOR CONTROLLING PATH OF CHARGING AND DATA COMMUNICATION AND ELECTRONIC DEVICE IMPLEMENTING THE SAME - An electronic device comprising: a first interface configured to connect to an external power supply device; a second interface configured to connect to a first external electronic device; and a control circuit operatively coupled to the first interface and the second interface, configured to: establish a first electrical path between the first interface and the second interface, when the first interface is connected to the external power supply device and the second interface is connected to the first external electronic device; disconnect the first electrical path; and provide a data signal to the first external electronic device while the first external device with power that is supplied by the external power supply device, wherein the data signal and the power are provided to the first external electronic device via the second interface. | 2017-06-15 |
