One is the 191 bits secure curve of ANSI X9.62 , elements in F2m field represented by polynomial basis, the other is the 148bits secure curve in our secure curve library elements in F2m field represented by optimal normal basis;

• 一条是ANSIX9.；62中的191bit的安全曲线，F_2m中的元素用多项式基表示，一条是我们安全曲线库中的148bit的安全曲线，F_2m中的元素用最优正规基表示；
