An Efficient and Secure Data Sharing Method Using Asymmetric Pairing with Shorter Ciphertext to Enable Rapid Learning in Healthcare

Table 3

A comparison of various symmetric- and asymmetric-pairing-based MCBE schemes.

Schemes									Pairing
	[4]			2		2		2			SP
[22]			2		2		1	2	SP
[16]			2		2		1	2	SP
[24]		m	1	1	1		1		AP
[23]			2		2		2		SP
Proposed			1	1			1	2	AP

SP: symmetric pairing; AP: asymmetric pairing.
