Efficient 2-Round General Perfectly Secure Message Transmission: A Minor Correction to Yang and Desmedt's Protocol

Qiushi Yang and Yvo Desmedt

Abstract: At Asiacrypt~'10, Yang and Desmedt proposed a number of perfectly secure message transmission protocols in the general adversary model. However, there is a minor flaw in the 2-round protocol in an undirected graph to transmit multiple messages. A small correction solves the problem. Here we fix the protocol and prove its security.
