Tables are defined to permit output masking for table look-ups to be carried out to resist power analysis attacks on cryptographic operations. The sample is added to the first portion. The transmit signal is a modulated signal with a base frequency sinusoidally modulated at a modulation frequency. Since a parasitic capacitance exists between associated bit lines, the electrical potential of a node is reduced to the ground level due to the coupling effect of the parasitic capacitance. The aromatic hydrocarbon units have substituents of the general formula R1SiR2R3R4, wherein R1 is optional and is a hydrocarbon or ether linking the silicon and the aromatic hydrocarbon, and R2, R3, and R4 are one or more of hydrogen, alkyl, and alkoxy, with the provision that no more than two may be hydrogen or alkyl.
