What is confusion and diffusion in cryptography with example?

WebIn cryptography, the avalanche effect is the desirable property of cryptographic algorithms, typically block ciphers [1] and cryptographic hash functions, wherein if an input is changed slightly (for example, flipping a single bit), the output changes significantly (e.g., half the output bits flip). WebApr 13, 2024 · An image encryption model is presented in this paper. The model uses two-dimensional Brownian Motion as a source of confusion and diffusion in image pixels. Shuffling of image pixels is done using Intertwining Logistic Map due to its desirable chaotic properties. The properties of Brownian motion helps to ensure key sensitivity. Finally, a … WebDec 6, 2024 · In 1949, Claude Shannon first proposed the ideas of confusion and diffusion in the operation of a cipher.
