abstract
MPC-in-the-head based protocols have recently gained much popularity and are at the brink of seeing widespread usage. With widespread use come the spectres of implementation issues and implementation attacks such as side-channel attacks. We show that implementations of protocols implementing the MPC-in-the-head paradigm are vulnerable to side-channel attacks. As a case study, we choose the ZKBoo-protocol of Giacomelli, Madsen, and Orlandi (USENIX 2016) and show that even a single leaked value is sufficient to break the security of the protocol. To show that this attack is not just a theoretical vulnerability, we apply differential power analysis to show the vulnerabilities via a simulation.
