20190140834 | Advanced Crypto Token Authentication - A system and method for authenticating an application that employs cryptographic keys and functions is provided with white box cryptography employed to secure the application, and to secure communications with the application. The white box includes a transformation of the application and the keys. A secure channel between the white box and a crypto token is used for communications. In some cases, the transformed keys can be employed in authenticating the white box to the crypto token. The presence of a valid crypto token can be periodically determined. In the presence of a valid crypto token, the white box can provide a verifiable message to a remote server. The remote server can verify the message and initiate a service. | 2019-05-09 |
20190140835 | Blind Hash Compression - Techniques are provided for blind hash compression, such as serving, from a computer server system and to a plurality of different computing devices remote from the computer server system, web code and code for reporting status of the computing devices; receiving from one or more of the computing devices, first data that indicates a parameter of the one or more computing devices, the first data in a compressed format; receiving from one or more others of the computing devices, second data that indicates the parameter of the one or more others of the computing devices, the second data in an uncompressed format; and compressing the second data and comparing the compressed second data to the first data to correlate the first data to the second data. The code for reporting status of the computing devices can include code for allowing the computing devices to determine whether to send the first or second data. | 2019-05-09 |
20190140836 | PROVISIONING TRUSTED EXECUTION ENVIRONMENT BASED ON CHAIN OF TRUST INCLUDING PLATFORM - Techniques are described herein that are capable of provisioning a trusted execution environment (TEE) based on (e.g., based at least in part on) a chain of trust that includes a platform on which the TEE executes. Any suitable number of TEEs may be provisioned. For instance, a chain of trust may be established from each TEE to the platform on which an operating system that launched the TEE runs. Any two or more TEEs may be launched by operating system(s) running on the same platform or by different operating systems running on respective platforms. Once the chain of trust is established for a TEE, the TEE can be provisioned with information, including but not limited to policies, secret keys, secret data, and/or secret code. Accordingly, the TEE can be customized with the information without other parties, such as a cloud provider, being able to know or manipulate the information. | 2019-05-09 |
20190140837 | Remote Management Method, and Device - A remote management method and a device, where the method includes receiving, by a subscription manager-data preparation (SM-DP+) server, a first identifier from a local profile assistant (LPA), searching for, by the SM-DP+ server, a remote profile management command corresponding to the first identifier, generating, by the SM-DP+ server, a first digital signature according to the first identifier and the remote profile management command, and sending the first digital signature and the remote profile management command to an embedded universal integrated circuit card (eUICC) using the LPA. | 2019-05-09 |
20190140838 | TECHNOLOGIES FOR PROVIDING CERTIFIED TELEMETRY DATA INDICATIVE OF RESOURCES UTILIZATIONS - Technologies for providing certified telemetry data indicative of resource utilizations include a device with circuitry configured to obtain telemetry data indicative of a utilization of one or more device resources over a time period. The circuitry is additionally configured to sign the obtained telemetry data with a private key associated with the present device. Further, the circuitry is configured to send the signed telemetry data to a telemetry service for analysis | 2019-05-09 |
