Description: 元胞自动机的虚拟程序
开发工具：Microsoft Visual Basic 6.0
运行平台：Windows OS
(VB编译，代码未优化,运行速度较慢)
词语解释：
CA，cellular automata，元胞自动机，或称细胞自动机。
模式(Pattern)，多个细胞构成的一个状态组合。
模型：
维度，二维四方网格
细胞，两种状态（活、死）；一个方格代表一个细胞。
邻居，Moore型(上、下、左、右、左上、右上、左下、右下)
规则，1)一个活着的细胞如果保持活的状态，那么它必需具有2至3个活的邻居，否则它就变成死的状态。2)一个死的细胞如果变成活的，那么它必需恰好有3个活的邻居。
程序功能：
1. 方格水平数量和垂直数量自由设置(最少为2，即2*2的网格)
2. 随机初始化细胞（细胞为活的概率可设置）
3. CA状态的演化，可自动逐步也可手动逐步。
4. 两种显示模式（用于研究可能的规律）
5. 可对CA状态进行编辑（操作类似简单的绘图）。
6. 模式。可以选择局部网格为模式；模式可以被旋转和翻转操作；模式可以被保存到文件和插入到网格。
7. 可以保存当前CA的状态到文件，也可载入已保存的CA状态。-Cellular Automata virtual procedure
Development tools: Microsoft Visual Basic 6.0
Platform: Windows OS
(VB compiler, the code is not optimized to run more slowly)
Words to explain:
CA, cellular automata, cellular automaton, or cellular automata.
Pattern (Pattern), consisting of a number of cells in a state of combination.
Model:
Dimension, two-dimensional grid Quartet
Cells, two states (living and dead) a grid on behalf of a cell.
Neighbors, Moore-type (upper and lower, left, right, left, right, left, bottom right)
Rules, 1) If a living cell to maintain a state of living, then it must have 2-3 living neighbors, otherwise it becomes a state of death. 2) If a dead cell becomes live, then it must have exactly three live neighbors.
Program features:
1. The number of grid levels and the number of free vertical settings (at least 2, which is 2* 2 grid)
2. Random initialization cells (the probability

Description: 提供一个cell-weraging constant false alarm rate (CA-CFAR)的算法，基于信号检测的方法。-We present a method for evaluating the performance of
cell-weraging constant false alarm rate (CA-CFAR) processors
which use the anplitude of echo signals rather than their
squared amplitude Results are presented for the case of Rayleigh
clutler/mise statistics for which some sirnulatiom have been
reported recently by other authors [:I. Detection probabilities are
evaluated for the case of a Rayleigh fluctuating target embedded
in Rayleigh clutter/noise for linear-law CA-CFAR processors.
These results are observed to be practically identical to those of
square-law CA-CFAR processors for which analytical expressions
are readily available. We also verify these observations using
Monte Carlo simulations. The same conelusion is reached in the
case of a nonfluctuating target embedded in Rayleigh clutter/noise
for which only simulation results are presented here.

Description: 写了一个文件加解密工具（VC9+OPENSSL）
CA程序：
生成2个RSA密钥对，分别保存为PEM格式，密码保护私钥，文件名为“RSAPrivateKey.pem”和“RSAPublicKey.pem”。
加密：
将指定明文文件加密，密文件格式自已定义，要求文件内容用对称算法（3des）加密，对称密钥（KEY）为随机生成，随机密钥用“RSAPrivateKey.pem”的公钥加密后，存放在密文文件头内（KEY1）；对明文文件做摘要计算（HASH），将计算结果用“RSAPublicKey.pem”的私钥加密后（SIGN），放到密文文件头内；文件头内有明文的原始长度信息。
解密:
将密文文件解密成明文文件，流程与加密相反，先用“RSAPrivateKey.pem”私钥解密（KEY1）数据，得出随机密钥（KEY）；用随机密钥对密文解密，得到明文文件；对明文文件进行摘要计算，得出HASH1；用“RSAPublicKey.pem”公钥解密SIGN，得出HASH2；HASH1与HASH2做对比，相同表示解密成功，不同表示解密失败。
密文文件头内可以保存原始加密人的信息以及解密人的信息，这样可以快速判断解密者是否有权限解密该密文文件，如果有权限则进行解密过程，否则直接提示没有权限解密。
-To write a file encryption and decryption tool (VC9+ OPENSSL)
CA procedures:
Generates two RSA key pairs, respectively, save for the PEM format, password-protected private key, the file named "RSAPrivateKey.pem" and "RSAPublicKey.pem".
Encryption:
The specified plaintext file encryption, secret self-definition file formats require the document to use symmetric algorithms (3des) encryption, symmetric key (KEY) is randomly generated, random key to use "RSAPrivateKey.pem" public key encryption, stored in the ciphertext header inside (KEY1) summary of the calculation of the plaintext file to do (HASH), the calculation results with the "RSAPublicKey.pem" private key encryption (SIGN), into ciphertext in the file header file header if there is express The original length of the message.
Decryption:
Decrypt the ciphertext into a plaintext file documents, processes and encrypt the contrary, the first to use "RSAPrivateKey.pem" decrypt the private key (KEY1) data, derived random k

Description: EJBCA是一个完整功能的证书认证程序，完全用 Java编写，使用J2EE(Java2 Enterprise Edition, Java2企业版)技术。它建造在J2EE平台之上，是一个开放的、健壮的、高性能的、平台独立的、灵活的和基于组件的CA，可以被单独使用或集成到其它J2EE应用程序中，并且它还提供了一个灵活强大的基于 Web的用户图形界面。由于它实现了WPKI中的几乎所有重要的部件，比如RA (Registration Authority，注册中心), CA(Certification Autohrity，认证中心)、CRL (Certification RemoveList，证书撤销列表)和证书存储数据库等，因此得到了广泛的应用 。-EJBCA is a fully functional Certificate program, entirely in Java, using J2EE (Java2 Enterprise Edition, Java2 Enterprise Edition) technology. It is built on a J2EE platform, is an open, robust, high-performance, platform independent, flexible, and component-based CA, can be used alone or integrated into other J2EE applications, and it provides a flexible and powerful Web-based graphical user interface. Because it implements WPKI in almost all the important parts, such as the RA (Registration Authority, Registration Center), CA (Certification Autohrity, Authentication Center), CRL (Certification RemoveList, certificate revocation list) and certificate storage database, it has been a wide range of applications.
