Abstract

See full text

According to an aspect of an embodiment operations may include receiving, by a server, message shares. The operations may also include generating, by the server, an aggregate hash share of the message shares. In addition, the operations may include receiving, by the server, a verification vector iteration from another server and generating another verification vector iteration based on: the received verification vector iteration, a permutation that corresponds to the server, and a masking vector that corresponds to the server. The operations may also include obtaining a verification hash that is based on the verification vector and participating in a multiparty computation to determine an aggregate hash. The operations may also include determining, as part of the multiparty computation, whether one or more of the servers is operating in an adverse manner based on whether the verification hash is equal to the aggregate hash.
