On Information-Theoretic Secure Multiparty Computation with Local Repairability

ePrint Report: On Information-Theoretic Secure Multiparty Computation with Local Repairability

Daniel Escudero, Ivan Tjuawinata, Chaoping Xing

In this work we consider the task of designing information-theoretic MPC protocols for which the state of a given party can be recovered from a small amount of parties, a property we refer to as local repairability.
This is useful when considering MPC over dynamic settings where parties leave and join a computation, a scenario that has gained notable attention in recent literature.
