Tóm tắt: The work investigates cheating prevention in secret sharing. It is argued that cheating is immune against cheating if the cheaters gain no advantage over honest participants by submitting invalid shares to the combiner. This work addresses the case when shares and the secret are taken from GF(p ). Two models are considered. The first one examines the case when cheaters consistently submit always invalid shares. The second modeldeals with cheaters who submit a mixture of valid and invalid shares.
