Quizplus · Accepted Answer

Challenge-response protocol is a common method used to verify the authenticity of a remote user. In this method, the system challenges the user to provide some information or demonstrate some knowledge that only the legitimate user possesses. The user's response is then authenticated by the system. This helps to counter threats such as identity theft and password guessing. Eavesdropping, Trojan horse, and denial-of-service attacks can also be used to compromise remote user authentication, but they are not typically countered by a specific protocol.
