Description: (繁体中文版)台湾出品不得多得的关于spa dpa 旁道攻击rsa算法的精彩论文。相对国内的一些翻译性质的、粗制滥造的论文，简直是一个天上一个地下。-As information technology has developed rapidly, it provides more convenient life for people. As the result, the security has become the main concern. Recently, user id and password are major methods to protect private information. However, the short password can be broken by hackers. Too long is not easy to memorize. Network traffic-analyzing tool provides the function to gain the user id and password while doing transaction via network. Therefore, low cost Smart Card including user name identification and cryptosystem algorithm has become new trend of
modern society.
The first object of this thesis is to present the design and implementati- on of a 512-bit RSA cryptosystem by using 8051 microcontroller. In RSA cryptosystem algorithm, modular exponentiation is the essential arithmetic operation. However, 8051 microcontroller does not provide the modular exponentiation. In order to complete RSA cryptosystem, this thesis has mentioned that using L-algorithm to transfer to modular mult

Description: 这个范例说明如何使用8051， LCD显示器和4ⅹ4的小键盘，制作一个密码锁。PORT 1 连接到LCD显示器的数据线。PORT 3 的P3.3,P3.4和P3.5分别连接到LCD显示器的控制线。PORT 2连接到4ⅹ4的小键盘，可以输入密码。执行修改密码或是时间的程序时，首先让LCD显示器显示出时间和日期。
当用户按下4ⅹ4小键盘的按钮 A 时，可以输入密码。如果密码正确时，就会让 P3.6的 LED 闪烁，表示打开锁。如果密码不正确时，LCD显示器就会显示出
"PASSWORD WRONG"。
当用户按下4ⅹ4小键盘的按钮 B时，可以修改时间。
当用户按下4ⅹ4小键盘的按钮 C时，可以修改密码。*/-This example illustrates how to use the 8051, LCD display and 4 ⅹ 4 small keyboard, create a password lock. PORT 1 to connect to the LCD display data. PORT 3 of P3.3, P3.4 and P3.5, respectively, connected to the control line LCD display. Connected to the PORT 2 of 4 ⅹ 4 small keyboard, you can enter a password. Change Password or time to implement the program, first of all, let LCD display shows time and date.
When the user press the keypad 4 ⅹ 4 button A, you can enter a password. If the password is correct, it will allow the LED flashes P3.6 that lock open. If the password is incorrect when, LCD display will show

Description: 设计以电磁继电器模拟密码锁，由单片机8051来控制锁的打开与闭合，由HD7279来管理器键盘及显示，密码从键盘输入，用8051来控制7279显示当前锁的状态信息及报警。本次设计用单片机开发系统来模拟密码锁的多种功能，密码由4-6位数字组成，当输入密码相符时开锁，输入三次不符报警，同时密码输入正确时可以修改密码，此时指示灯亮。开锁单片机开发出开关量，通过光电耦合器控制，打开密码锁。报警则由单片机发出报警信号，控制音频放大电路发出报警声音。-Designed to simulate electromagnetic relay locks, by the microcontroller 8051 to control the lock open and closed, by the HD7279 to manage the keyboard and display device, the password from the keyboard input to control the 7279 with 8051 shows the current lock status information and alarms. The microcontroller development system designed for use to simulate the lock of a variety of functions, the password from 4-6 digits, when the lock when the password match, enter the three inconsistent with the police, at the same time when you enter the correct password can modify the password, this time indicator light . SCM developed unlocking switch volume control through the optocoupler, open the lock. Alarm alarm signal sent by the MCU to control the audio amplifier circuit alarm sounds.
