The KEM component being relatively easy to implement, in most cases, in an MPC friendly manner. Thus …
NettetWe discuss the design of symmetric primitives, in particular Pseudo-Random Functions (PRFs) which are suitable for use in a secret-sharing based MPC system. We consider three different PRFs: the Naor-Reingold PRF, a PRF based on the Legendre symbol, and a specialized block cipher design called MiMC.
