Differential power analysis(DPA) has become a ma jor system security concern.To achieve high levels of security with low power and die area costs,a novel Dual-voltage single-rail dynamic logic(DSDL) design is proposed.The proposed scheme can reduce power dissipation and obtain extremely well-balanced power consumption.The charge sharing mechanism is used for voltage transfer in the internal nodes during the evaluation of the design.Dual power supply voltages are used with positive feedback to speed up the evaluation process.A 4-bit micro Substitution box(SBOX) of the Advanced encryption standard(AES) algorithm has been implemented to verify the security of the proposed logic design.The experimental results proved the security and the efficiency of the proposed DSDL,which can reduce power dissipation by up to 20% and occupies at most 83% of the silicon area when compared with previous state-of-the-art countermeasures.
