WebJan 15, 2024 · Scrambling is a technique used in digital electronics to provide a known sequence of bits to allow for synchronization and detect errors. The code to implement scrambling will depend on the specific requirements of the system. Here is a simple … WebOct 24, 2010 · Firstly, we generate integer sequence which as parameters and iteration times of general Arnold map to shuffle the positions of each bit-plane pixels by using 4D hyper-chaotic system. Then we generate random integer vectors to shuffle the positions of the rows and columns for each bit-plane image by using two dimensional Logistic map.

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. [ 1] proposed an image-encryption algorithm with dual scrambling of the pixel position and bit. postterm babies will have hypoglycemia due to

WebAug 24, 2016 · This paper lead forward to a new approach of text scrambling algorithm for encryption using artificial intelligence technique of cubical text and its random rotation type with angle. At first the original message is converted into six face cubical form (3 × 3 × 3 cube) and the cube is chosen as it is easy to scramble the message in cubical form. WebAug 10, 2024 · In this letter, the strategies of shift-register based scrambling and block-wise scrambling (using matrix multiplications) are assessed for a Gaussian wiretap channel scenario w.r.t. the security gap metric. We show that the former leads to an unequal protection of communicated message bits. WebThe scrambler performing this scrambling function can be implemented simply using a few shift registers and exclusive-OR gates; and the descramblers reconstructing the original … post term abortion definition
