摘要
Described is a system for mobile proactive secret sharing amongst a set of servers. A First protocol distributes a block of secret data among the set of servers, the block of secret data including shares of data. Each server holds one share of data encoding the block of secret data. A Second protocol periodically refreshes shares of data such that each server holds a new share of data that is independent of the previous share of data. A Third protocol reveals the block of secret data. Shares of data are periodically erased to preserve security against the adversary. The Second protocol provides statistical security or non-statistical security against the adversary.
