Abstract
Techniques for memory assisted inline encryption/decryption are described. An example includes an encryption data structure engine to provide a key, data, and a tweak to the encryption/decryption engine, wherein the encryption data structure engine is to: read an index value from an encryption data structure lookup data structure entry using an address, the entry to include the index value and a guest page physical address (GPPA), retrieve, based on the index value, an entry from the encryption data structure, the entry to include a logical block address (LBA) base, a key identifier, and at least one GPPA in a sequence of GPPAs, generate a LBA using a position of the GPPA from the encryption data structure lookup data structure entry in the sequence of GPPAs, and retrieve a key based on the key identifier, wherein the encryption engine to encrypt data using the retrieved key, and the generated LBA.
