is that iteration times are not affected by the map s capacity 的一个优点是迭代次数不受映射表容量的影响。
when iteration times are over 303, the computing accuracy is over 当迭代次数大于300时,计算精度达到以上。
listing 1 shows an example that measures the iteration time of a collection using the standard approach 清单1显示了一个测量用标准方式遍历集合所用时间的例子:
thus, it is very difficult to decode the hashing algorithm; the security is enhanced via using the selected matrix and iteration time as the secret keys 将所选用的矩阵和迭代次数作为浮水印的密钥,提高了算法的安全性。
