[Crack HackDSA

Description: 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。

Description: ElGamal算法既能用于数据加密也能用于数字签名,其安全性依赖于计算有限域上离散对数这一难题。   密钥对产生办法。首先选择一个素数p,两个随机数, g 和x,g, x < p, 计算 y = g^x ( mod p ),则其公钥为 y, g 和p。私钥是x。g和p可由一组用户共享。   ElGamal用于数字签名。被签信息为M,首先选择一个随机数k, k与 p - 1互质,计算 -首先选择一个随机数k, k与 p- 1互质,计算   a = g^k ( mod p )   再用扩展 Euclidean 算法对下面方程求解b:   M = xa+ kb ( mod p- 1 )   签名就是( a, b )。随机数k须丢弃。   验证时要验证下式:   y^a* a^b ( mod p ) = g^M ( mod p )   同时一定要检验是否满足1<= a < p。否则签名容易伪造。   ElGamal用于加密。被加密信息为M,首先选择一个随机数k,k与 p- 1互质,计算   a = g^k ( mod p )   b = y^k M ( mod p )   ( a, b )为密文,是明文的两倍长。解密时计算   M = b/a^x ( mod p )   ElGamal签名的安全性依赖于乘法群(IFp)* 上的离散对数计算
