The probability of Eve’s impersonation being detected varies with n. The x-axis stands for the number of bits of the authentication code \(k_{ide}\), namely n. The y-axis represents the probability of Eve’s impersonation attack being detected. It should be noted that the protocol does not work when \(n=1\). However, for a complete demonstration of the trend of the probability of Eve being found, this figure retains this case
