| University | University of Wollongong (UOW) |
1. Consider the following key exchange protocol which is a variant of the Diffie-Hellman protocol. Each user P has a secret key sk_P=x_P and public key pk= gx_P mod p.
1: A B: gr_A mod p
2: B A: gr_B mod p
In the protocol, r_A and r_B are randomly chosen in each session by A and B. The shared key for communication is defined as K = gr_Ax_B + gr_Bx_A mod p.
