  • In-place encryption of a swap file on a host machine
    Patent number: 11455182
    Abstract: Systems and methods are described for encrypting a swap file in a computer system. The swap file can be encrypted by a background process executing on the computer system. Processing of paging swapping operations occurs independently and separately of the background encryption of the swap file. Processing a page swapping operation can include decrypting or encrypting data to be swapped involved in the paging operation depending on the paging operation and whether or not the data to be swapped is encrypted or not.

  • IN-PLACE GUEST-AGNOSTIC ENCRYPTION OF A RUNNING VIRTUAL MACHINE
    Publication number: 20200349260
    Abstract: Systems and methods are described for encrypting the virtual disk in a virtual machine (VM). The virtual disk can be encrypted by a background process executing on the host machine that hosts the VM. Input/output operations (I/Os) to the virtual disk issued by a guest operating system (OS) executing on the VM can be intercepted on the hypervisor of the host machine and processed during the background encryption. Processing of the I/Os occurs independently and separately of background encryption of the virtual disk. Processing an I/O can include decrypting or encrypting data involved in the I/O depending on the location on the virtual disk targeted by the I/O.
