A method for sharing data encryption keys among a plurality of storage systems is disclosed. The method generates, by a first storage system, a data encryption key for encrypting data sent from the first storage system to cloud storage. The method stores the encrypted data in the cloud storage in the form of an encrypted data object. In certain embodiments, the first storage system stores an Internet Protocol (IP) address of a second storage system belonging to a same key sharing network as the first storage system. The method replicates, from the first storage system to the second storage system, the data encryption key. The second storage system retrieves the encrypted data object from the cloud storage and decrypts the encrypted data in the encrypted data object using the data encryption key received from the first storage system.

A system for security key rotation in a cloud computing environment is disclosed. The system performs steps to at least initiate, at a predetermined interval, a call to determine whether to initiate generation of a public-private key pair for a client application. The system determines whether to initiate generation of the public-private key pair for the client application and based on determining to initiate generation of the public-private key pair for the client application, transmits a control signal requesting generation of the public-private key pair The system generates the public-private key pair and transmits a private key associated with the public-private key pair to a secure storage location for later retrieval by the client application and transmits a public key associated with the public-private key pair to a public key service for later retrieval by a client associated with the client application.

Various embodiments are generally directed to continuous authentication of a user to a digital service based on activity of a contactless card positioned proximate to a computing device on which the digital service operates. For example, a series of periodic status messages may be provided between a client device and the contactless card to verify whether the contactless card remains active, wherein authorization to access the digital service continues while the contactless card is active, and terminates when the contactless card is inactive.

An endpoint for trusted fabrication, the endpoint including at least one secure controller configured for connection to a wide area network; and at least one untrusted controller configured for local communication, wherein the endpoint is configured for connection to a fabricator and further configured to receive digitally-signed data specifying at least one item for manufacture; verify the digitally-signed data; and direct the fabricator to manufacture the at least one item after verifying the digitally signed data. A method for trusted on-demand manufacturing, the method including receiving, at an endpoint connected to a fabricator, digitally signed data describing at least one item for manufacture; verifying, at the endpoint, the digitally signed data; and manufacturing the at least one item using the digitally signed data after verifying the digitally signed data, wherein the endpoint comprises at least one secure controller and at least one untrusted controller.

A method performed by a user device is disclosed. The method comprising generating a secret and measuring a biometric template of a user operating the user device. The method then generates a plurality of secret shares of the secret and of the biometric template. The user device then transmits the secret shares of the secret and of the biometric template to a plurality of recovery devices. After, the user device may then initiate a recovery of the secret and measure a biometric measurement of the user. Data of the biometric measurement may be transmitted to the plurality of recovery devices, where the recovery devices perform a partial computation. The user device use the plurality of partial computations to determine a match between the biometric template and the biometric measurement. If the two biometrics match, the user device can reconstruct the secret using shares of the secret from the recovery devices.

A combined security access system for a building that includes a controllable building component. The system includes a combined security access device connected to the building component. The access device further includes: a processor; a first memory device connected to the processor; a second memory device connected to the processor; and a wireless interface module connected to the processor. The access device may be connected to an external electronic device, and the external electronic device communicates with the processor of the access control system to control the building component.

A scheme for securely transferring a patient data file to an intended recipient regardless of a transfer mode selected by a sender. Encryption system executing at the sender device is operative to encrypt each plaintext data line of a file, one by one, using a symmetric key and a starting IV that is incremented per each line, resulting in corresponding ciphertext lines added to an encrypted file. A hash is generated based on the encrypted file. An encrypted header containing the symmetric key, starting IV and the hash is generated using a public key of the recipient, which is appended to the encrypted file. The encrypted header and associated encrypted file are transmitted to the recipient in any manner. Upon receipt, the recipient decrypts the encrypted header using a private key to obtain the symmetric key, starting IV and the hash, which are used by the recipient to validate and decrypt the encrypted file on a line-by-line basis.

A diamond asset comprising one or more diamonds and an encryption chip is used to asset-back a cryptographic token that can be used to conduct transactions. The cryptographic token is written to a blockchain using a smart contract that is configured to enable a transaction associated with the token in response to two or more of: a signature by the encryption chip, a signature by the owner of the diamond asset, and a validation of a visual layout of the diamond asset.

Methods in a cloud object store facilitate strong data encryption, customer-management of object (encryption) keys, reductions in latency, globally-distributed object storage, and handling of streamed uploads. A method for encrypting objects stored in a cloud includes encrypting each object with a unique encryption (object) key. The plaintext object keys are generated in advance of uploads. The plaintext object keys can be stored in an object database in the cloud. Alternatively, the plaintext object keys can be provided to a customer's HSM, encrypted, and returned to the cloud, such that encrypted object keys, encrypted by the customer, are stored in the cloud. The cloud can alternatively encrypt the customer's object keys with a master key for the customer, which is then encrypted by the customer's HSM before being stored in the cloud. Proxies are also deployed for efficiently communicating with customer security modules.

Techniques are described for securely managing computing resources in a computing environment comprising a computing service provider and a remote computing network. The remote computing network includes computing and network devices configured to extend computing resources of the computing service provider to remote users of the computing service provider. The network devices include a trusted network device that includes a root of trust. The trusted network device detects that a new device is communicatively coupled to a port on the trusted network device. The trusted network device determines that the new device is not authorized to access computing resources at the remote computing network. The port is isolated at the trusted network device.
