| Abstract: | In this paper we consider the problem of identifying cheaters in secret sharing schemes. Rabin and Ben-Or presented a perfect and unconditionally secure secret sharing scheme in which the honest participants are able to identify the cheaters. We present a similar scheme, but one in which the information distributed to each participant is smaller. |
