Abstract
An encryption device can include a tweaking value manager that is configured to generate an array of tweaking values corresponding to the array of data blocks based on a tweaking encryption key, a first encryption unit that is configured to encrypt a first portion of the array of data blocks into a first portion of encrypted data blocks based on corresponding tweaking values and a data encryption key, a second encryption unit that is configured to encrypt a second portion of the array of data blocks into a second portion of encrypted data blocks based on corresponding tweaking values and the data encryption key, and a data block combiner that is configured to combine the first portion of encrypted data blocks and the second portion of encrypted data blocks into an array of encrypted data blocks.
