In telecommunications, a scrambler is a device that transposes or inverts signals or otherwise encodes a message at the sender's side to make the message unintelligible at a receiver not equipped with an appropriately set descrambling device. Whereas encryption usually refers to operations carried out in the digital domain, scrambling usually refers to operations carried out in the analog domain. Scrambling is accomplished by the addition of components to the original sig… WebJul 9, 2024 · Bit scrambling is an image-encryption method that changes the pixel value by scrambling the bits of the pixel value. It has been paid growing attention by scholars in recent years. In 2014, Deng et al.
