DPA resistance is achieved by authentication before decryption and by key rolling.   Authentication before decryption, using the RSA algorithm, prevents an adversary from acquiring additional data per key by substituting their own data for the data contained in the boot image. Key rolling limits the amount of data encrypted on any given key. The amount of data encrypted by a key is configurable by the user.
