A Masked Correlated Power Noise Generator as a Second Order DPA Countermeasure to Secure Hardware AES Cipher

International audienceActually, only one Second Order Differential Power Analysis (SO-DPA) countermeasure has been published. This solution is multiple masking solutions. It consume a lot of area and need to design two independent True Random Number Generator (TRNG). This work proposes a new SO-DPQ countermeasure for AES cipher. It combines a simple masking solution with the CPNG countermeasure. Our solution optimizes area overhead and reduces the total number of TRNG. The robustness of the novel method is demonstrated with experimental method using FPGA implementation
