S1. User_ID[A] chooses a random r in ZN, computes x r 2 (modulo N ) and sends x to User_ID[B]. S2. User_ID[B] chooses a random bit-vector b (s0, s1, . . . , bk21)Zk,2 using the uniform distribution sends it to User_ID[A]. Qk 1 S3. User_ID[A] returns y to User_ID[B] where y r i 0 sbi (modulo N). i Qk 1 bi Q S4. User_ID[B] computes z y2 i 0 vi (modulo N) r 2 k 1 s2bi vbi (modulo N) and i i 0 i accepts User_ID[A] s identity as valid if z x. The probability of successfully masquerading is now 22k. The protocol was modi ed to derive a signature scheme; suppose h is a hashing function with values in Zk,2 and xky denotes the concatenation of x and y.
