Malicious Security for SCALES: Outsourced Computation with Ephemeral Servers

ePrint Report: Malicious Security for SCALES: Outsourced Computation with Ephemeral Servers

Anasuya Acharya, Carmit Hazay, Vladimir Kolesnikov, Manoj Prabhakaran

SCALES (Small Clients And Larger Ephemeral Servers) model is a recently proposed model for MPC (Acharya et al., TCC 2022). While the SCALES model offers several attractive features for practical large-scale MPC, the result of Acharya et al. only offered semi-honest secure protocols in this model.


We present a new efficient SCALES protocol secure against malicious adversaries, for general Boolean circuits. …
