1.用RS-232的零MODEM的連接法連好兩機(jī)的連線; 2.用DOS的MODE命令設(shè)置好兩機(jī)的通訊格式,兩機(jī)的通訊格式必須一致。 3.用DEBUG的0命令將一數(shù)發(fā)送到串行口(2F8H-3F8H),然后在另一臺機(jī)上用I命令讀入串行口的內(nèi)容。如果發(fā)送的內(nèi)容與接收的內(nèi)容一致,說明兩機(jī)已連好線,否則必須檢查連線,直到兩機(jī)可通訊為止; 4.編一程序,將一臺機(jī)的鍵盤輸入的鍵值通過RS-232C口送到另一臺機(jī),并在CRT上顯示鍵值; 5.編一程序,通過RS-232C口進(jìn)行一臺機(jī)到另一臺機(jī)的文件復(fù)制。

Digital Signature Algorithm (DSA)是Schnorr和ElGamal簽名算法的變種,被美國NIST作為DSS(DigitalSignature Standard)。算法中應(yīng)用了下述參數(shù): p:L bits長的素?cái)?shù)。L是64的倍數(shù),范圍是512到1024; q:p - 1的160bits的素因子; g:g = h^((p-1)/q) mod p,h滿足h < p - 1, h^((p-1)/q) mod p > 1; x:x < q,x為私鑰 ; y:y = g^x mod p ,( p, q, g, y )為公鑰; H( x ):One-Way Hash函數(shù)。DSS中選用SHA( Secure Hash Algorithm )。 p, q, g可由一組用戶共享,但在實(shí)際應(yīng)用中,使用公共模數(shù)可能會帶來一定的威脅。簽名及驗(yàn)證協(xié)議如下: 1. P產(chǎn)生隨機(jī)數(shù)k,k < q; 2. P計(jì)算 r = ( g^k mod p ) mod q s = ( k^(-1) (H(m) + xr)) mod q 簽名結(jié)果是( m, r, s )。 3. 驗(yàn)證時(shí)計(jì)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,則認(rèn)為簽名有效。 DSA是基于整數(shù)有限域離散對數(shù)難題的,其安全性與RSA相比差不多。DSA的一個(gè)重要特點(diǎn)是兩個(gè)素?cái)?shù)公開,這樣,當(dāng)使用別人的p和q時(shí),即使不知道私鑰,你也能確認(rèn)它們是否是隨機(jī)產(chǎn)生的,還是作了手腳。RSA算法卻作不到。

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單片機(jī)由于低格低、處理能力強(qiáng),在信號分析、數(shù)據(jù)采集等很多領(lǐng)域得到了廣泛應(yīng)用,在目標(biāo)系統(tǒng)中使用各種規(guī)格的液晶或CRT顯示器也越來越多。因此在這樣的單片機(jī)系統(tǒng)中引入鼠標(biāo),將會方便操作,提高工作效率。鼠標(biāo)內(nèi)核本質(zhì)上是一個(gè)二維的角度或位移信號檢測裝置,耗電極少、可靠性高、價(jià)格低廉,可能在許多場合發(fā)揮作用。鼠標(biāo)與主機(jī)之間通過RS-232標(biāo)準(zhǔn)串行接口進(jìn)行通信,信息傳送是單方向、無條件、無應(yīng)答連續(xù)進(jìn)行的。此外80C196的UART不直接支持鼠標(biāo)的接口協(xié)議,在程序設(shè)計(jì)中必須予以注意。本文主要探討80C196單片機(jī)與Microsoft兼容鼠標(biāo)接口程序的設(shè)計(jì)實(shí)現(xiàn)。
