Abstract
A method for encrypting data in one or more data blocks is provided. The method receives a first data block to be written to a physical storage that includes one or more physical disks. The method applies a first random tweak to data indicative of the first data block to generate a first encrypted data block, and writes the first encrypted data block and the first random tweak to a first physical block of the physical storage. The method receives a second data block to be written to the physical storage. The method then applies a second random tweak, different than the first random tweak, to data indicative of the second data block to generate a second encrypted data block, and writes the second encrypted data block and the second random tweak to a second physical block of the physical storage.
