RANDOMIZATION OF ENCRYPTION OF FILE BLOCKS

A method for providing randomized encryption for file blocks including receiving a plurality of file blocks, selecting at least one encryption scheme for the plurality of file blocks, determining a first encryption order for the plurality of file blocks, encrypting, at a first time, the plurality of...

Zusammenfassung:A method for providing randomized encryption for file blocks including receiving a plurality of file blocks, selecting at least one encryption scheme for the plurality of file blocks, determining a first encryption order for the plurality of file blocks, encrypting, at a first time, the plurality of file blocks with the at least one encryption scheme in the first encryption order to produce a first plurality of encrypted file blocks, determining a second encryption order for the plurality of file blocks, the second encryption order being different from the first encryption order, and encrypting, at a second time, the plurality of file blocks with the at least one encryption scheme in the second encryption order to produce a second plurality of encrypted file blocks.
