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。

dsa数字签名 系统功能需求: 1.对文件进行签名,生成一个独立于原文的签名文件; 2.可以对文件进行签名,在文件后追加签名信息; 3.具有密钥管理的功能,比如密钥的生成、导入、导出; 4.可以对word文档实施操作,对word文档的内容进行签名; 5.能够比对已经实施的签名,防止进行重复的签名,以防止重放攻击; 6.可以对已经签名的文件进行单独的源文件和签名信息的分离操作。(DSA digital signature System functional requirements: 1. Sign the document and generate a signature file independent of the original text. 2. The document can be signed and the signature information can be added after the document. 3. It has the function of key management, such as key generation, import and export. 4. Word documents can be operated and the contents of Word documents can be signed. 5. Ability to compare existing signatures and prevent duplicate signatures to prevent replay attacks; 6. It is possible to separate the source file from the signature information of the signed file.)
