Commitment Phase. In this step the nodes exchange the blocks they generated by quantizing the FFT coefficients. Let Bs1 = b1, b1, ..., b1 , denote the blocks generated at an arbitrary sensor s1. Here R is the index of the blocks and R = 20 in our case. As the blocks form the basis of the final key, they cannot be exchanged in the open. Therefore, each block is hashed using a one-way hash function before being transmitted. The commitment phase is carried out in two steps.
