Abstract: Automated Turing Tests (ATTs), also known as human-in-the-loop techniques,
were recently employed in a login protocol by Pinkas and Sander (2002) to protect against
online password-guessing attacks. We begin by noting that this, and other protocols involving
ATTs, are susceptible to minor variations of well-known middle-person attacks. We discuss
techniques to address such attacks, and present complementary modifications in a new historybased
protocol with ATTs. Analysis indicates that the ... (Update)
