A system disclosed herein may receive, from an application associated with a client identification, a request to perform a cryptographic operation with a specified application key, identify a gateway associated with the client identification, identify a respective characteristic of each self-encrypting key management service of a plurality of self-encrypting key management services that correspond to the gateway, identify a self-encrypting key management service with a characteristic satisfying a threshold criterion, and send the request to the identified self-encrypting key management service.

Self-encrypting key management system

The technology disclosed herein enables a method to receive an indication of a change to an operating mode of a device from a first operating mode to a second operating mode, and identify a cryptographic item stored at a memory of the device, wherein the cryptographic item corresponds to an identification of the device signed with a digital signature, and wherein the digital signature is based on a private key that is inaccessible to the device. On response to receiving the indication of the change to the operating mode of the device, the method can modify the cryptographic item stored at the memory, and operate the device in the second operating mode based on the modified cryptographic item. The indication of the change to the operating mode of the device can correspond to a detection of a change in a function of the device.

Erasing a cryptographic hem in a memory of a device in response to a change of an operating mode of the device

A method may include obtaining, by a processing device, a workflow object that includes a plurality of workflow entity objects and one or more data objects, and executing a workflow by identifying, from the application objects, an application object that corresponds to a first application, wherein the workflow associates the application with at least one of the data objects, determining, whether the first application has permission to access the data object according to a data policy associated with the data object, wherein the data policy specifies one or more data access criteria, wherein the first application has permission to access the data object in response to one or more of the workflow entity objects that are associated with the data object satisfying the data access criteria, and responsive to determining that the first application has permission to access the data object, executing the first application in a secure enclave.

Confidential computing workflows

A request may be received from an application for a performance of an operation associated with a cryptographic key that is stored at a secure enclave. A plugin of the secure enclave may be identified from the request for performance of the operation. The operation associated with the cryptographic key may be performed by using the plugin of the secure enclave to generate an output within the secure enclave. The output generated within the secure enclave and based on the plugin may be provided to the application.

Runtime encryption plugin for a key management system

A request to perform an operation with a cryptographic item may be received. A request for approval to perform the requested operation with the cryptographic item may be transmitted to a set of entities based on a policy associated with the cryptographic item. Indications of approval to perform the requested operation may be received from corresponding entities of the set of entities. A determination as to whether a number of the received indications of approval to perform the requested operation with the cryptographic item satisfies a threshold number may be made. In response to determining that the number of the received indications of approval from the corresponding entities of the set of entities satisfies the threshold number, the requested operation may be performed with the cryptographic item.

Obtaining quorum approval to perform an operation with a cryptographic item of a key management system

A request to issue a digital certificate may be received. A hash value corresponding to an application that has provided the request for the digital certificate may be identified. A determination may be made as to whether the hash value corresponding to the application matches with a known hash value. In response to determining that the hash value corresponding to the application matches with the known hash value the digital certificate may be issued to the application.

Issuing a certificate based on an identification of an application

Authentication information at a first portion of encrypted data may be identified. A cryptographic key may be derived based on a combination of an identification of the first portion of the received encrypted data and a master key. Additional authentication information may be generated based on a combination of the derived cryptographic key and another portion of the received encrypted data. The encrypted data may be verified by comparing the authentication information at the first portion of the received encrypted data with the generated additional authentication information. In response to verifying the received encrypted data, a second cryptographic key may be derived based on a combination of an identification of the another portion of the encrypted data and the master key. The other portion of the received encrypted data may be decrypted by using the second cryptographic key.

Management of and persistent storage for nodes in a secure cluster

An indication of a change to an operating mode of a device may be received. A cryptographic item stored at a memory of the device may be identified. In response to receiving the indication of the change to the operating mode of the device, the cryptographic item stored at the memory may be modified. The device may operate in the changed operating mode based on the modified cryptographic item.

Erasing a cryptographic item in a memory of a device in response to a change of an operating mode of the device

An input data may be received. Memory pages may be identified where each of the memory pages includes one or more cache lines. A first index table that includes cache lines may be generated from the memory pages based on the input data. Subsequently, an output data may be provided based on a particular cache line from the cache lines of the first index table.

Indexing of memory pages to provide secure memory access

A first connection between a first network server and a second network server may be established where the first connection is based on a connection key stored at a secure location of the first network server. A request for one or more cryptographic keys may be transmitted from the first network server to the second network server. The first network server may receive the one or more cryptographic keys from the second network server over the first connection. The one or more cryptographic keys from the second server may be stored at the secure location of the first network server that is storing the connection key used to establish the first connection.

Secure key caching client

A cryptographic key may be received or generated at a self-encrypting key management service application where the cryptographic key is received from another application provided on a server associated with the self-encrypting key management service application. The cryptographic key may be stored at a secure enclave corresponding to the self-encrypting key management service application. A request for a performance of a cryptographic operation associated with the cryptographic key may be received from the other application provided on the server. The cryptographic key at the secure enclave corresponding to the self-encrypting key management service application may be retrieved. The cryptographic operation may be performed with the cryptographic key to generate an output that is provided to the other application.
