By offering similar levels of security,the Elliptic Curve Cryptosystem(ECC) provides greater efficiency than either integer factorization systems or discrete logarithm systems,in terms of computational overheads,key sizes,and bandwidth.

• 在提供相同安全的条件下 ,椭圆曲线密码体制比其它公钥密码体制需要更小的密钥长度、计算开销和带宽 ,具有更广泛的适用性。
