Abstract: Systems, devices, and techniques are disclosed for cryptographic key migration. A tenant host may determine a first Key Management Service (KMS) indicated as storing a cryptographic key associated with the tenant host from a new KMS mapping. The tenant host may send a request for the cryptographic key associated with the tenant host to the first KMS. The tenant host may receive an indication from the first KMS that the first KMS does not store the cryptographic key.

Abstract: Systems and methods are for confidentially and securely provisioning data to an authenticated user device. A user device may register an authentication public key with an authentication server. The authentication public key may be signed by an attestation private key maintained by the user device. Once the user device is registered, a provisioning server may send an authentication request message including a challenge to the user device. The user device may sign the challenge using an authentication private key corresponding to the registered authentication public key, and may return the signed challenge to the provisioning server. In response, the provisioning server may provide provisioning data to the user device. The registration, authentication, and provisioning process may use public key cryptography while maintaining confidentiality of the user device, the provisioning server, and then authentication server.

Abstract: A method comprises conveying a downhole tool in a production tubing within a casing that is around a wall of a wellbore formed in a subsurface formation, wherein cement is placed in an annulus defined between the casing and the wall of the wellbore. The downhole tool includes at least one unipole receiver and at least one of a unipole and a monopole transmitter. The transmitter and receiver are mounted on a rotatable portion of the downhole tool. The method includes performing the following operations at at least two azimuthal positions, emitting an acoustic transmission outward toward the cement and detecting an acoustic response that is in response to the acoustic transmission propagating through the production tubing and the casing and into the cement. The acoustic response includes casing extensional waves, casing non-extensional waves, and tubing waves. The method includes evaluating the cement based on the casing extensional waves.

Abstract: In a system for verifying transactions, when a user with a portable communication device nears a resource provider location, the portable communication device provides an indication to a transaction processing system of its proximity to the location. The portable communication device then provides a universally unique identifier (UUID) of a base station of the resource provider to the transaction processing system, which generates a hash using the UUID and a primary account number (PAN) of a portable transaction device that is associated with the portable communication device. When the user conducts a transaction with the portable transaction device at the provider, the provider generates a separate hash from the UUID and the PAN and sends the hash to the transaction processing system. A match between the hashes is taken into account as a positive indicator that the transaction is not fraudulent and the resource provider is complying with the system.
