Illustration of time cost for each duplication numbers when the threshold of the model size is 1024 (B=10). As encoding duplication number increases, the time cost for Encryption increases linearly while the cost for RotSum decreases approximately by log scale, and the other parts are stationary. In our implementation environment, the total time cost is minimal when duplication number is 2
