Side-Channel Analysis of Keccak and Ascon

This thesis is about side-channel analysis of the SHA-3 competition winner Keccak and a similar algorithm Ascon. During the operation of such an algorithm on a device information will leak in many different ways. In this thesis we only look at the information that is leaked by the power consumption of a device. This leakage can be exploited with a technique called DPA. With DPA one tries to obtain a small part of secret data, usually the secret key using a many power traces with random input messages and the key in each trace. We verified a theoretical attack with experiments on an actual chip. We also compared an attack on MAC-Keccak implemented on an FPGA to an ASIC. For Ascon which was implemented on an FPGA we crafted a similar attack as Keccak. With DPA being a very powerful tool for an attacker hardware needs to be designed with countermeasures against this. Threshold implementations are such countermeasures, we tried to attack an threshold implementation on an FPGA of Ascon to see if it was possible with a feasible amount of power traces. Finally, we look a the noise components in a power trace and how much effect the effect of electrical noise is with Ascon.
