Modeling and Simulation of Side-Channel Attacks to Cryptographic Devices
A side-channel attack (SCA) is a cryptanalytic attack that uses cryptographic devices' physical behaviors such as electromagnetic emanation and voltage fluctuation while processing cryptographic operations. Designing cryptographic devices secure against SCA is becoming more important as the devices are getting implemented on a wider variety of electronic products. Modeling and simulation of SCA will give useful knowledge such as how information leaks from the cryptographic devices and/or what parts of the device leak information. With the knowledge, designing cryptographic devices secure against SCA could become easier. The modeling and simulation of SCA will also give a prediction in vulnerabilities of their products to SCA. We developed an equivalent circuit modeling methodology of cryptographic devices that allows designers to simulate SCA vulnerability. Model parameters are identified both from the design information of cryptographic devices and measurements after the fabrication.
