Digital Signal and Image Processing Using MATLAB The most important theoretical aspects of image and signal processing (ISP) for both deterministic and random signals are covered in this guide to using MATLAB® . The discussion is also supported by exercises and computer simulations relating to real applications such as speech processing and fetal-heart–rhythm tracking, and more than 200 programs and functions for numerical experiments are provided with commentary.

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。
