Example implementations include a system of secure decryption by virtualization and translation of physical encryption keys, the system having a key translation memory operable to store at least one physical mapping address corresponding to at least one virtual key address, a physical key memory operable to store at least one physical encryption key at a physical memory address thereof; and a key security engine operable generate at least one key address translation index, obtain, from the key translation memory, the physical mapping address based on the key address translation index and the virtual key address, and retrieve, from the physical key memory, the physical encryption key stored at the physical memory address.

Systems and methods that allow secure application-driven arbitrary compute in storage devices in a cloud-based computing system are provided. A computing system including a compute controller configured to: (1) provide access to host compute resources, and (2) operate in at least one of a first mode or a second mode is provided. The computing system may further include a storage controller configured to provide access to storage systems including storage components, at least one compute component, and at least one cryptographic component. In the first mode, the host compute resources may be configured to execute at least a first operation on at least a first set of data stored in at least one of the storage components. In the second mode, the at least one compute component may be configured to execute at least a second operation on at least a second set of data.

In one example in accordance with the present disclosure, a method may include receiving, by a processor on a system on a chip (SoC), a request to encrypt a subset of data accessed by a process. The method may also include receiving, at a page encryption hardware unit of the SoC, a system call from an operating system on behalf of the process, to generate an encrypted memory page corresponding to the subset of data. The method may also include generating, by the page encryption hardware unit, an encryption/decryption key for the first physical memory address. The encryption/decryption key may not be accessible by the operating system. The method may also include encrypting, by the page encryption hardware unit, the subset of data to the physical memory address using the encryption/decryption key and storing, by the page encryption hardware unit, the encryption/decryption key in a key store.

Aspects of a storage device including a memory and an encryption core are provided. The storage device may be configured for providing secure data storage, as well as one or more post-processing operations to be performed with the data. The encryption core, which may be configured to decrypt data, may control execution of one or more post-processing operations using the data. A read command received from a host device may include a tag associated with data identified by the read command. When encrypted data is retrieved from memory according to the read command, the encryption core may decrypt the encrypted data and provide the decrypted data for post-processing based on the tag. A corresponding post-processing operation may return a result when executed using the decrypted data. Rather than raw data identified by the read command, the result may be delivered to the host device in response to the read command.
