Chapter 5: Propagation and Correlation
نویسنده
چکیده
In this chapter we treat difference propagation and input-output correlation in Boolean mappings and iterated Boolean transformations. Difference propagation is specifically exploited in differential cryptanalysis (DC), invented by Eli Biham and Adi Shamir [BiSh91]. Input-output correlation is exploited in linear cryptanalysis (LC), invented by Mitsuru Matsui [Ma93]. Both DC and LC were successfully applied on the block cipher DES [Fi77]. DC was the first chosenplaintext attack, LC the first known-plaintext attack more efficient than exhaustive key search for DES.

Implication of Quantum Effects on Non-Linear Propagation of Electron Plasma Solitons
We have studied the electron exchange-correlation effect on thecharacteristics of the two-component unmagnetized dense quantum plasma withstreaming motion. For this purpose, we have used the quantum hydrodynamic model(including the effects of a quantum statistical Fermi electron temperature) for studyingthe propagation of an electrostatic electron plasma waves in such th...
متن کاملChapter 2 Propagation Fundamentals & Literature Search
The performance of wireless communication systems depends on the radio wave transmission path between the transmitter and the receiver. Unlike wired channels that are stationary and predictable, radio channels are extremely random. In addition, electromagnetic wave propagation characteristics vary significantly over different frequency bands. Therefore it is vital to thoroughly understand the p...
متن کامل1 Fundamentals of Optics
In this chapter, we discuss some of the fundamentals of optics. We first cover the electromagnetic (EM) spectrum, which shows that the visible spectrum occupies just a very narrow portion of the entire EM spectrum. We then discuss geometrical optics and wave optics. In geometrical optics, we formulate the propagation of light rays in terms of matrices, whereas in wave optics we formulate wave p...

In Chapter I, mptallographic evidence of the existence of the surface layer is given. Using etch-pit techniques on an ironsilicon alloy, it is shown that the dislocition concentration of strained specimens decreases away from the surface. In Chapter II, a relationship is given between the surface-layer stress and fatigue failure. When surface-layer stress attains a critical value, the specimens...
