Based on the systematic block codes, we propose a (t,n) multi-secret sharing scheme. Compared with the previous works, our scheme has the advantages of smaller communication overhead, easy generator matrix construction and non-disclosure of users secret shares after multiple secret reconstruction operations. These advantages make the practical implementation of our scheme very attractive.
