Abstract

We investigate the problem of Secure Multiparty Computation (SMC) in a synchronous system with Byzantine failures where processes have access to trusted hardware. While previous solutions needed a majority of well-behaving processes to solve SMC, we construct an algorithm that solves SMC for an arbitrary number of Byzantine processes. We do this by refining and combining multiple established concepts from the literature: (1) We introduce a dynamic association between processes and trusted hardware modules in the hybrid system model of Fort et al. (TrustedPals model), (2) we utilize the primitive of Uniform Reliable Broadcast for information dissemination between trusted hardware modules, and (3) we use (and slightly adapt) the concept of Sealed Computation as an abstraction of trusted hardware modules.
