Glitches occur in every CMOS circuit. Consequently, the currently known masking schemes for CMOS gates do not prevent DPA attacks. ...
There are many articles and patents on the masking of logic gates. However, the existing publications assume that a masked logic gate switches its output no more than once per clock cycle. ...

We subsequently show that the side-channel leakage of the masked multipliers can be prevented by fulfilling timing constraints for 3 · n XOR gates in each GF (2 n ) multiplier of an AES S-box. ...
Motivated by this fact, we pinpointed which parts of masked AES S-boxes cause the glitches that lead to side-channel leakage. ...
It is important to point out that it is exclusively this effect that accounts for the side-channel leakage of the masked AND gate. ...
