Batch secret sharing for secure multi-party computation in asynchronous network. (English) Zbl 1214.94067
Summary: This paper proposes an efficient batch secret sharing protocol among \(n\) players resilient to \(t < n/4\) players in an asynchronous network. The construction of our protocol is along the line of Hirt’s protocol which works in a synchronous model. Compared with the method of using secret share protocol \(m\) times to share \(m\) secrets, our protocol is quite efficient. The protocol can be used to improve the efficiency of secure multi-party computation (MPC) greatly in asynchronous network.
