1.用RS-232的零MODEM的连接法连好两机的连线; 2.用DOS的MODE命令设置好两机的通讯格式,两机的通讯格式必须一致。 3.用DEBUG的0命令将一数发送到串行口(2F8H-3F8H),然后在另一台机上用I命令读入串行口的内容。如果发送的内容与接收的内容一致,说明两机已连好线,否则必须检查连线,直到两机可通讯为止; 4.编一程序,将一台机的键盘输入的键值通过RS-232C口送到另一台机,并在CRT上显示键值; 5.编一程序,通过RS-232C口进行一台机到另一台机的文件复制。

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 < q,x为私钥 ; y:y = g^x mod p ,( p, q, g, y )为公钥; H( x ):One-Way Hash函数。DSS中选用SHA( Secure Hash Algorithm )。 p, q, g可由一组用户共享,但在实际应用中,使用公共模数可能会带来一定的威胁。签名及验证协议如下: 1. P产生随机数k,k < q; 2. P计算 r = ( g^k mod p ) mod q s = ( k^(-1) (H(m) + xr)) mod q 签名结果是( m, r, s )。 3. 验证时计算 w = s^(-1)mod q u1 = ( H( m ) * w ) mod q u2 = ( r * w ) mod q v = (( g^u1 * y^u2 ) mod p ) mod q 若v = r,则认为签名有效。 DSA是基于整数有限域离散对数难题的,其安全性与RSA相比差不多。DSA的一个重要特点是两个素数公开,这样,当使用别人的p和q时,即使不知道私钥,你也能确认它们是否是随机产生的,还是作了手脚。RSA算法却作不到。

Atmel’s AT91SAM7FP105 is a low pincount FingerChip processor based on the 32-bit ARM RISC processor. It features a on-chip biometric engine performing enrollment verification and identification, an internal record cache of up to 25 records and a secure command protocol over USB, SPI, UART. This protocol enables an external host system or processor to control the onchip bioengine functions, manipulate the record cache, and securely export record cache records for external storage. Together with the FingerChip sensor device AT77C104B, it forms an embedded, secured biometric turnkey solution.

80C196单片机由于低格低、处理能力强,在信号分析、数据采集等很多领域得到了广泛应用,在目标系统中使用各种规格的液晶或CRT显示器也越来越多。因此在这样的单片机系统中引入鼠标,将会方便操作,提高工作效率。鼠标内核本质上是一个二维的角度或位移信号检测装置,耗电极少、可靠性高、价格低廉,可能在许多场合发挥作用。鼠标与主机之间通过RS-232标准串行接口进行通信,信息传送是单方向、无条件、无应答连续进行的。此外80C196的UART不直接支持鼠标的接口协议,在程序设计中必须予以注意。本文主要探讨80C196单片机与Microsoft兼容鼠标接口程序的设计实现。
