Method and apparatus for storing encrypted data files across distributed storage media

摘要

A method for distributing data to a plurality of storage locations in a computing network is provided. The method includes receiving, at a processor in the computing network, input data and an input random cryptovariable, transforming, at the processor, the input data and the input random cryptovariable into encrypted output using Da Yen processing, and distributing the encrypted output to the plurality of storage locations. The present design further includes a method for decrypting encrypted blocks of data distributed over a plurality of storage locations in a computing network. The method includes receiving, at a processor in the computing network, a plurality of cipher/key word pairs, and transforming, at the processor, the plurality of cipher/key word pairs and a salt key word into plaintext using Da Yen processing.

1. A computing network system, comprising:
a plurality of storage locations; and a Da Yen processor configured to receive input data and an input random cryptovariable; wherein the Da Yen processor is further configured to transform the input data and the input random cryptovariable into encrypted output using Da Yen processing and distribute the encrypted output to the plurality of storage locations; wherein Da Yen processing comprises:
using a stream cipher to generate a plurality of key words;using a first nonzero byte of one key word as a higher order byte of a dth plaintext coefficient; andfilling a lower order portion of the one key word.
