Abstract
Described is a system for verifiable secret sharing amongst a plurality of servers, including a dealer server and one or more recipient servers. In operation, the dealer server encrypts a secret s using a polynomial and a hash tree with points on the polynomial as leaves. The dealer broadcasts to recipient servers hash tree data, root of the hash tree, and shares of the secret. Through an evaluation process the recipient servers are verified such that upon verification, the recipient servers reconstruct the secret s.
