| Research Abstract |
In the model of Perfectly Secure Message Transmission schemes (PSMT), there are n channels between the sender and receiver who share no keys. Adversaries are infinitely powerful, and can corrupt some subset of n channels. In this research, round optimum PSMT and almost PSMT have been constructed for some class of adversaries.
