The Challenge Handshake Authentication Protocol (CHAP) is used to verify the identity of a peer in a 3-way handshake and is usually embedded in other protocols, commonly PPP. Several extensions (MS-CHAP) exist to allow the encryption of link layer packets via CHAP authenticated connections. In this paper I will describe how CHAP may be attacked, gaining unauthorized access to CHAP protected dia...

This paper exploits a novel cheating game the “Mind Game” to show how a subtle variation in the rules of the game affects cheating. In both variants of the game, cheating is invisible because subjects make their choices purely in their minds. The only difference rests on the order of the steps in which subjects should play the game. I find that subjects cheat significantly less when they have t...

Punishment is an important deterrent against cheating in cooperative interactions. In humans, the severity of cheating affects the strength of punishment which, in turn, affects the punished individual's future behaviour. Here, we show such flexible adjustments for the first time in a non-human species, the cleaner wrasse (Labroides dimidiatus), where males are known to punish female partners. ...

Surveys and questionnaires are frequently used by psychologists, social scientists, and epidemiologists to collect data about behavior, attitudes, emotions, and so on. However, when asked about sensitive topics such as their sexual behavior or illegal activity, some respondents lie or refuse to answer. The randomized response method was developed to reduce these evasive answer biases by guarant...

This paper addresses strategies for the stable roommates problem, assuming that a stable matching is chosen at random. We investigate how a cheating man should permute his preference list so that he has a higher-ranking roommate probabilistically. In the first part of the paper, we identify a necessary condition for creating a new stable roommate for the cheating man. This condition precludes a...
