To test this motivation for conformity, Sherif (1936) needed a situation in which the physical environment lacked ready-made yardsticks for understanding, so that the operation of social standards could be observed His solution was to take advantage of the autokinetic effect the apparent motion of a stationary spot of light in a dark room The idea was to place a group of participants in this type of situation and ask them to make estimates of the light s movement Participants, of course, were not informed that the light s movement was illusory When tested individually, participants varied considerably in their estimates, from virtually no movement to more than 10 inches He then brought together three participants who had previously made estimates in private, and asked them to announce their individual judgments aloud and in succession.

While the plan-based theory of speech acts was a major step forward, it was recognized that a theory of speech acts should be rooted in a more general theory of rational action. This observation led Cohen and Levesque to develop a theory in which speech acts were modelled as actions performed by rational agents in the furtherance of their intentions (Cohen and Levesque, 1990b).The foundation upon which they built this model of rational action was their theory of intention, described in Cohen and Levesque (1990a). The formal theory is summarized in 1 2 , but, for now, here is the Cohen-Levesque definition of requesting, paraphrased in English.

It is necessary to guarantee the security of sensor networks as well as sensing applications in hostile environments, especially when the failures of these applications (eg, critical infrastructure protection) may result in catastrophic events with impacts affecting safety, security, the economy, and society at large In other words, sensor networks and sensing applications should work as expected, and offer gracefully degrading services in hostile environments where there are malicious attackers, even if some nodes fail or are compromised However, several unique features of sensor networks make it very challenging to provide security in sensor networks First, sensor nodes are typically resource constrained due to the need to lower the cost As a result, it is usually undesirable to use expensive mechanisms such as public key cryptography on such nodes Second, sensor networks are often deployed in an unattended fashion, possibly exposed to physical attacks.

Despite their initial differences, participants converged fairly quickly (often within three trials) on a single estimate that functioned as a group standard for the light s movement Sherif went on to show that after a group de ned reality for participants, they continued to adhere to the group judgment even after they left the group (see also Alexander, Zucker, & Brody, 1970) Deutsch and Gerard (1955) recognized that people can conform for different reasons and formally distinguished between normative in uence, which captures the essence of the Asch situation, and informational in uence, which re ects participants motivation in the Sherif situation Normative in uence refers to conformity in an attempt to gain approval, whereas informational in uence refers to conformity in an attempt to gain clear knowledge about reality Sometimes it is dif cult to determine which basis of conformity is operative in a given situation.

Sensor nodes may be captured, and any secret information on a captured node can potentially be disclosed to attackers Thus, any security mechanism for sensor networks has to be resilient to compromised nodes Third, most sensor network applications depend on local communication and computation because of the resource constraints on sensor nodes However, a determined attacker may attack any node in a sensor network and use the information gathered from the compromised nodes to attack noncompromised ones in a certain region This further adds to the imbalance between the threat and the defense in sensor networks Security in sensor networks has attracted a lot of attention in the past several years Key management is one of the most fundamental security services for sensor networks The performance of several traditional key management approaches has been examined on different hardware platforms [2].
