Problems solved by technology

For example, the availability of the host processor to perform other work may be reduced while encrypting the DAR with this separate service, thereby degrading the throughput and / or latency performance of the computing device
Also, the communication paths linking the host processor and separate services may be compromised, thereby reducing the effectiveness of encryption techniques

Abstract

An improved system for providing transparent, in-line encryption of data-at-rest (DAR) stored by a host controller of a host device. An encryption core is instantiated in a hardware device physicallycoupled to a system board within the host device. The encryption core includes a storage device proxy, an encryption engine, and a plurality of host device proxies. Each host proxy among the pluralityof host proxies interfaces the host controller to one persistent storage device among a plurality of persistent storage devices within the host device via the storage device proxy. The storage deviceproxy exposes the plurality of persistent storage devices to the host controller as a single persistent storage device. The encryption core encrypts and decrypts DAR exchanged between the host controller and an encrypted storage device.

Description

technical field [0001] The present invention relates generally, but not exclusively, to systems and computing devices with integrated persistent storage media, and more particularly to methods for transferring data-at-rest (DAR: Data-at- Rest) provides transparent online encryption (in-line encryption) technology system. Background technique [0002] Integrated storage media, such as embedded multimedia card (eMMC) storage devices, are commonly used to provide computing devices with integrated persistent memory for storing data. Computing devices often use such integrated storage media to store data at rest (DAR). DAR generally refers to data that is not processed by the computing device's host processor and does not reside in the computing device's system memory. Existing methods for encrypting DAR are generally out-of-band encryption techniques. For example, existing methods for encrypting DARs may be implemented as a separate service utilized by a host processor of a c...
