U a computes (3) e i ⊕ f i = [ h (ID i || x s ) ⊕ r i ] ⊕ f i = [ h (ID i || x s ) ⊕ h (PW i ⊕ K i ) ⊕ f i ] ⊕ f i = [ h (ID i || x s ) ⊕ h (PW i ⊕ K i ) ] to obtain [ h (ID i || x s ) ⊕ h (PW i ⊕ K i ) ]. U a guesses PW a as user's possible password and computes M1 a = [ e i ⊕ f i ] ⊕ h(PW a ⊕ K i ).
But if M 3 a = M 3, then it provides U a with the exact password PW i of C i. U a computes (4) e i ⊕ f i = [ h (ID i || x s ) ⊕ r i ] ⊕ f i = [ h (ID i || x s ) ⊕ h (PW i ⊕ K i ) ⊕ f i ] ⊕ f i = [ h (ID i || x s ) ⊕ h (PW i ⊕ K i ) ] to obtain [ h (ID i || x s ) ⊕ h (PW i ⊕ K i ) ]. U a guesses PW a as user's possible password and computes M1 a = [ e i ⊕ f i ] ⊕ h(PW a ⊕ K i ).
