Abstract
Described is a system for implementing proactive secret sharing. The system uses a Secret-Share protocol to distribute, by a computing device, a block of secret data comprising shares of secret data among a set of computing devices, wherein each computing device in the set of computing devices holds an initial share of secret data. The system uses at least one Secret-Redistribute protocol to periodically redistribute the plurality of shares of secret data among the set of computing devices, wherein each computing device in the set of computing devices holds a subsequent share of secret data from the block of secret data that is independent of the initial share of secret data. Finally, a Secret-Open protocol is initialized to reveal the block of secret data.
