Table 3

Performance comparison.

	File information	Preprocess		Proof generation		Verification	Multiple proof verification
	Size	Time	Tag size	Time	Size	Time	Time
Scheme [9]	1 GB	86 s	13 MB	45 ms	288 byte	45 ms	88 ms
Our scheme	1 GB	82 s	6 MB	61 ms	320 byte	46 ms	51 ms

Note that we compare with scheme [9] in the parameter to 150 and the size of challenged set to 240.
