Abstract

Inline cryptography techniques implemented with a storage accelerator may enable encryption of data in transit between the storage accelerator and the storage device. In one example, the storage accelerator maintains local I/O context information for I/O commands and modifies the data pointer (e.g., PRP) in the I/O command sent to the storage device to include a reference (e.g., index) to the I/O context information. For a read command, the storage accelerator receives encrypted data from the SSD along with the modified data pointer. The storage accelerator may then determine the appropriate key and tweak value based on the modified data pointer, decrypt the data with the key and tweak value, and send the decrypted data to the host device without waiting for all data to be received from the storage device.
