Shannon's theory of confusion and diffusion
Webb6 dec. 2024 · Confusion and Diffusion In 1949, Claude Shannon first proposed the ideas of confusion and diffusion in the operation of a cipher. Confusion is the property of a cipher whereby it provides no clue regarding the relationship between the ciphertext and the key. Webb1. One way is to look at how many bits of the outputs are modified if you modify, say t bits in the input. Actually, a function from { 0, 1 } n to { 0, 1 } m such that modifying t bits in …

Webb13 apr. 2016 · The Henon map is used for confusion and the Lorenz equation for diffusion. Apart from the Lorenz equation, another matrix with the same size as the original image is generated which is a complex function of the original image. This matrix which is configured as a diffusion matrix permits two stages of diffusion. Webb13 apr. 2024 · Security of medical images over an unsecured channel is a challenging task, and for this, several methods have been designed recently. The present paper is also in the same direction, and is an attempt to improve the security of the existing methods. In this paper, a cryptosystem is proposed, which performs encryption and decryption in the CBC …
