Pairing based cryptography New random point exchange key protocol

Piaring based cryptography (PBC) is one of the latest cryptographic protocols, PBC is based on pairing functions that are mapping two points on an elliptic curve into a finite field, pairing is a non-degenerate bilinear map. The most practical property of PBC is bi-linearity: In this work, we will show that the bi-linearity property above is also a pairing, and we will see how to use this application with our input points
$P$
and Q in order to randomize these points to become more secure, and how to return to our original points
$P$
and Q, we will present the protocol to show how random point keys can be exchanged, and also the algorithm for calculating these keys, and finally we will give a brief comparison between our method and some other exist method.
