【摘要】 给出了基于椭圆曲线上离散对数问题的伪随机合成器的构造，并证明了其安全性．由于基于椭圆曲线上离散对数问题的密码体制安全性高，实现速度快，且密钥量小，因而文中的构造方法更有效更多还原

【Abstract】 We present a parallel construction of synthesizers based on the discrete log problem on elliptic curves defined over finite fields. Our construction is more efficient, since the cryptosystems based on discrete logarithm problems over elliptic curves are characterized by high security, high speed, and small secret key.更多还原
