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。

This discussion will attempt to outline some truths and common misconceptions about digital audio watermarking. It will survey the intrinsic obstacles that such technology is required to overcome, shedding light on its performance criteria, compromises and limitations. While doing so, it will also survey a few common types of applications, hopefully leading to a clear understanding as to the appropriateness of such technology and its expertise within multimedia content protection.
