$$e:G_1\times G_1\rightarrow G_2$$
In symmetric pairing-based cryptography with groups$(G_1,G_2)$ of prime order $q$ and $a,b \in Z_q$
Will the size of random generator $P$ from$ G_1$ and $a$ be same? I think it is different. I don't know why.

$\begingroup$ @fkraiem. They are for pairing-based cryptography. $\endgroup$ – myat Oct 12 '16 at 4:46
