Executive Summary

Deniable encryption is an important cryptographic primitive, essential in all cryptographic protocols where a coercive adversary comes to play with high potential. Deniable encryption plays a key role in the internet/electronic voting, electronic bidding, electronic auctions and secure multiparty computation. In this paper, a practical efficient receiver deniable encryption scheme based on BCP commitment scheme and idea of Klonowski et al. is proposed. The proposed scheme is a one-move scheme without any pre-encryption information required to be sent between the sender and the receiver prior to encryption.
