Lately, the attacks on online banking and electronic commerce applications are on the rise. These attacks are targeting at the vulnerabilities found at the client-side of a clientserver communication. Unfortunately, the traditional security mechanisms are not efficient enough in preventing these attacks. Man-in-the-browser attack is an example of such attacks. In this type of attack, an attacker tries to take advantage at the vulnerabilities caused by the client's browser extension. This attack is able to manipulate the information contained in a transaction without the user's consent. In this paper, an enhanced remote authentication protocol is proposed to mitigate the attack. Experiments were conducted in order to test the proposed protocol. From the experiments, it was found that the proposed protocol is able to mitigate the attack successfully.
