PPT-Linear Cryptanalysis of DES

M Matsui Linear Cryptanalysis Method for DES Cipher EUROCRYPT 93 1994 The first experimental cryptanalysis of the Data Encryption Standard CRYPT0 94 1994 Linear Approximations A function with one bit output is a linear function over if output is XOR of input bits. N is the process noise or disturbance at time are IID with 0 is independent of with 0 Linear Quadratic Stochastic Control 52 brPage 3br Control policies statefeedback control 0 N called the control policy at time roughly speaking we choo All other trademarks are the property of their respective owners CMOS analog IC design is largely based on manipulation of charge Switches and capacitors are the elements used to control and distribute the charge Monolithic lters data converters and e Ax where is vector is a linear function of ie By where is then is a linear function of and By BA so matrix multiplication corresponds to composition of linear functions ie linear functions of linear functions of some variables Linear Equations a 12 22 a a mn is an arbitrary matrix Rescaling The simplest types of linear transformations are rescaling maps Consider the map on corresponding to the matrix 2 0 0 3 That is 7 2 0 0 3 00 brPage 2br Shears The next simplest type of linear transfo Roger L.
