TLDA: An Efficient Two-Layered Data Authentication Mechanism for Content-Centric Networking

Table 3

Time comparison for RSA signing, verifying, and hashing to a segment of 4Kbytes, 2Kbytes, and 1Kbytes. (Timings are the average of one million executions.) RSA signature operation makes use of SHA-256 for message hashing.

	Segment Size
	4Kbytes	2Kbytes	1Kbytes
RSA 1024 Signing	1.9236 ms	1.8659 ms	1.7832 ms
RSA 1024 Verifying	0.3508 ms	0.2955 ms	0.2624 ms
RSA 2048 Signing	11.2315 ms	10.9907 ms	10.8255 ms
RSA 2048 Verifying	0.7487 ms	0.6983 ms	0.6753 ms
SHA-256	0.05071 ms	0.02556 ms	0.01329 ms
