scanhosts
- 现在一个机房的主机已经达到了一定数量,进行网络管理时,常常需要确定当前网络中处理活动状态的主机。本设计的目标就是编制程序,利用ICMP的回送请求和回送响应,来发现指定网段中的活动主机。 本设计的主体思想是使用ICMPECHO数据包来探测指定网段内的活动主机。具体方法是:通过简单的发送一个ICMPECHO(Type 8)数据包到目标主机,如果ICMPECHOReply(ICMPtype0)数据包接受到,说明主机是存活状态。如果没有就可以初步判断主机没有在线或者使用了某些过滤设备过滤了ICMP的

gudianmima
- 古典密码中,主要的思想为移位算法及置换算法。 1.移位密码 密钥K为整数,且取值空间为0到25;加密函数:x = x + k (mod 26);解密函数:x = x - k (mod 26)。当K=3时,为凯撒密码。 2.仿射密码 密钥对由a、b组成,整数a满足 gcd(a, 26) = 1,整数b的取值空间为0到25;加密函数:x = ax + b(mod 26);解密函数:x = a*y - a*b (mod 26)。当a=1,b=3时,为凯撒密码。 3.维吉
dwgpass
- dwg加密小程式(LSP) 1,将要进行加密的图纸另外复制一份,切记!!! 2,在autocad中,打开要加密的图纸。 3,点击 autocad 菜单 “工具” -》 “加载应用程序” ,加载 lockup.lsp。 4,加载后会出现提示对话框,点确定。 5,在autocad中,键入 lockup ,回车。 6,英文提示“是否进行加密?” ,输入 y ,回车。 7,余下的提示,都回车,加密完成,保存图纸。

DSA
- Digital Signature Algorithm (DSA)是Schnorr和ElGamal签名算法的变种,被美国NIST作为DSS(DigitalSignature Standard)。算法中应用了下述参数: p:L bits长的素数。L是64的倍数,范围是512到1024; q:p - 1的160bits的素因子; g:g = h^((p-1)/q) mod p,h满足h < p - 1, h^((p-1)/q) mod p > 1; x:x
