對(duì)稱密碼體制的發(fā)展趨勢(shì)將以分組密碼為重點(diǎn)。分組密碼算法通常由密鑰擴(kuò)展算法和加密(解密)算法兩部分組成。密鑰擴(kuò)展算法將b字節(jié)用戶主密鑰擴(kuò)展成r個(gè)子密鑰。加密算法由一個(gè)密碼學(xué)上的弱函數(shù)f與r個(gè)子密鑰迭代r次組成。混亂和密鑰擴(kuò)散是分組密碼算法設(shè)計(jì)的基本原則。抵御已知明文的差分和線性攻擊,可變長(zhǎng)密鑰和分組是該體制的設(shè)計(jì)要點(diǎn)。

This document is intended to serve as an introduction to Wavelet processing through a set of Matlab experiments. These experiments will gives an overview of three fundamental tasks in signal and image processing : signal, denoising and compression. These scripts are selfs contents (needed additional Matlab functions can be downloaded while reading the lectures). Each one of these five lectures should take between 1h and 2h in order to tests the various features of the scripts. One should copy/paste the provided code into a file names e.g. tp1.m, and launch the script directly from Matlab comand line > tp1 . Some of the scripts contains "holes" that you should try to fill on your own. I also provide the complete correction of these lectures as a set of Matlab scripts, but you should try as much as possible to avoid using them.

基于MSP430單片機(jī)TimerB的數(shù)字->模擬信號(hào)轉(zhuǎn)換的設(shè)計(jì).利用MSP430定時(shí)器B產(chǎn)生PWM,然后再通過(guò)RC濾波,得到直流或交流電壓信號(hào).此方法成本低廉,可靠性高,易于使用.
