Abstract
Efficient memory management can be provided in a multi-tenant virtualized environment by encrypting data to be written in memory by a virtual machine using a cryptographic key specific to the virtual machine. Encrypting data associated with multiple virtual machines using a cryptographic key unique to each virtual machine can minimize exposure of the data stored in the memory shared by the multiple virtual machines. Thus, some embodiments can eliminate write cycles to the memory that are generally used to initialize the memory before a virtual machine can write data to the memory if the memory was used previously by another virtual machine.
