Multivariate Analysis Exploiting Static Power on Nanoscale CMOS Circuits for Cryptographic Applications
Latest nanometer CMOS technology nodes have highlighted new issues in security of cryptographic hardware implementations. The constant growth of the static power consumption has led to a new class of side-channel attacks. Common attacks exploiting static power use an univariate approach to recover information from cryptographic engines. In our work, a multivariate approach based on information theoretic security metrics is presented. The temperature-dependence helps to exploit more information leakage from the hardware implementation.
