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，是一种较为常见的加密算法，它是基于1984年提出的公钥密码体制和椭圆曲线加密体系。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。在加密过程中，生成的密文长度是明文的两倍，且每次加密后都会在密文中生成一个随机数K。-The ElGamal algorithm is a more common encryption algorithm, which is based on the 1984 public key cryptosystem and elliptic curve cryptography system. Both digital signature can also be used for data encryption, its security relies on computational finite field discrete logarithm problem. Generated during the encryption process, the length of the ciphertext is plaintext twice, and each encryption will generate a random number K in the ciphertext. Platform: |
