Tapping alert protocol

Abstract

This paper proposes a new protocol called tapping alert protocol (TAP), which detects if any computer is eavesdropping on the network. When tapping is detected, it alerts the network users on the danger of tapping. In designing the protocol, a model for an attacker is developed who sniffs the network and breaks down the proposed protocol, and the requirements on the protocol in terms of efficiency and security are defined. We also describe how to detect if a network interface card on a remote computer is in the sniffing mode. The proposed protocol employs cryptographic schemes to guarantee authentication of the code monitoring tapping operation and integrity of the data being sent. Finally, the proposed protocol can protect authorized users from illegal eavesdropping on the network.
