Outline of Final Research Achievements |
We have studied the design of side-channel attack (SCA) resistant cryptographic implementations based on the signal-to-noise ratio (SN ratio) of side-channel leakage, using an FPGA implementation of the standard block cipher AES as an evaluation target. First, we proposed a method for identifying the signal-to-noise ratio of side-channel leakage and established a method for identifying the sources of side-channel leakage in cryptographic circuits from the design information of the cryptographic circuit. Furthermore, we showed the possibility of controlling SCA resistance by designing transfer coefficients of side-channel leakage paths based on the signal-to-noise ratio.
