METHOD OF ENCRYPTING A DATA STREAM

摘要

The disclosure relates to a method of encrypting or of decrypting a binary data stream by generating a binary encryption stream and combining by a reversible logic operation each bit of the binary data stream with a bit of the binary encryption stream, the generation of the binary encryption stream including generating an input block by applying a cryptographic function using a secret key to a data block, and generating the binary encryption stream from the input block by combining the bits of the input block with each other by logic operations in a manner so as to prevent the input block from being determined from the binary encryption stream.
