Deniable Encryption using One Time Pads

Deniable Encryption allows a sender and receiver having already performed some encrypted communication, to produce a fake message from the cipher text, when coerced by any third party hence tricking the coercer to believing it to be legit, keeping the real message private. The main goal of deniable encryption is to ensure that the deniability of sender and receiver remains intact even after interception of the message by an adversary, thus providing an inherent utility to resist the coercion in an indirect way. In this paper we try to propose a deniable encryption mechanism using One Time Pads in such a way that in case the sender and receiver are coerced to release the key to any third party, they can produce a fake message from a given cipher text thus providing complete deniability regarding a given message, moreover the design using one time pad ensures that the privacy of the original message in not compromised due to the generation of the fake message.
