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.
