Abstract-Side channel attacks are known to be efficient techniques to retrieve secret data. In this context, this paper concerns the evaluation of the robustness of triple rail logic against power and electromagnetic analyses on FPGA devices. More precisely, it aims at demonstrating that the basic concepts behind triple rail logic are valid and may provide interesting design guidelines to get DPA resistant circuits which are also more robust against DEMA.
Differential Power Analysis (DPA) is a powerful Side-Channel Attack (SCA) targeting as well symmetric as asymmetric ciphers. Its principle is based on a statistical treatment of power consumption measurements monitored on an Integrated Circuit (IC) computing cryptographic operations. A lot of works have proposed improvements of the attack, but no one focuses on ordering measurements. Our proposal consists in a statistical preprocessing which ranks measurements in a statistically optimized order to accelerate DPA and reduce the number of required measurements to disclose the key.
