—Research on sensor networks has become much more active and is currently being applied to many different fields. However since sensor networks are limited to only collecting and reporting information regarding a certain event, and requires human intervention with that given information, it is often difficult to react to an event or situation immediately(More)
With the security requirements of networks, biometrics authenticated schemes which are applied in the multi-server environment come to be more crucial and widely deployed. In this paper, we propose a novel biometric-based multi-server authentication and key agreement scheme which is based on the cryptanalysis of Mishra et al.'s scheme. The informal and(More)
The biological reduction of N(2) to give NH(3) may occur by one of two predominant pathways in which nitrogenous N(x)H(y) intermediates, including hydrazine (N(2)H(4)), diazene (N(2)H(2)), nitride (N(3-)) and imide (NH(2-)), may be involved. To test the validity of hypotheses on iron's direct role in the stepwise reduction of N(2), model systems for iron(More)
