Abstract
Described, is system for mobile proactive secret sharing. The system initializes a RobustShare protocol to distribute a block of secret data among a set of servers comprising n servers. The block of secret data comprises a plurality of shares of data, wherein each server in the set of servers holds one share of data encoding the block of secret data. At least one Block-Redistribute protocol is initialized to protect against at least one adversary that attempts to corrupt the set of servers. During a Block-Redistribute protocol, the set of servers periodically refreshes its plurality of shares of data such that each server holds a new share of data that is independent of the previous share of data. Finally, a Reco protocol is initialized to reveal the block of secret data.
