Off-The-Record (OTR) Security Protocol Application in Cloud Environment

The Pretty Good Privacy protocol is the most preferred choice for a safe and encrypted communication between two or more parties since it uses encrypted messages for the communication. However, the Off-the-Record (OTR) protocol fits better than PGP protocol as it does not fit well due to some of its characteristics. In the real world, physical communication has some characteristics that do not match with nature of PGP protocol. That offset in aspects was the stimulus to create a new kind of communication protocol: OTR. As the name says, “Off-the-Record” protocol tries to create distance from the message and its sender.When this distance is created, every message sent is unofficial and the sender can negate his correlation to it. The sender can make a statement and, in the future, deny any relations with it. Although this is the main premise of OTR, there is a list of additional characteristics that we are addressed in this paper. We also address the differences between OTR and some of the most used protocols in Internet of things (IoT) sector and why should IoT network use it.
