Recently, Wu-Chieu proposed an improvement to their original scheme, in order to make the scheme withstand impersonation attacks.

Accordingly, the current letter demonstrates the vulnerability of Wu-Chieu's modified scheme to an off-line password guessing attack and evaluates the efficiency of their schemes and related schemes.
