sigfis message sends corresponding asoddns :(d (m,r,s) to Bob. Suppose Eve intercepts (m,r, s). Eve chooses h with god(h,p– 1) = 1 and assigns ri = rh mod p and si srih-r- mod p-1. (a) Show that the message m1 = mr¡r-1 has (m1,r1, $1) as a valid signature. (b) This method allows Eve to forge a signature on the message m1. Why should this not cause
