Abstract
A method for encrypting and decrypting data, that includes using an encryption key and an address associated with a memory device or a software instance. The method for encrypting and decrypting data may be performed by a hypervisor or by a configured processor. The method may include receiving a read or write request specifying an address; performing a first lookup, in an address mapping table, to identify a memory module address of a memory module associated with the address; performing a second lookup to identify an encryption key associated with the read or write request; generating a decryption or encryption request that includes the memory module address; and the encryption key; and sending the decryption or encryption request to the memory module.
