Abstract:
Recently wireless sensor networks have been drawing much attention of network researchers because of their wide 
applications in a lot of areas, especially in military fields. To provide security sevices in sensor networks in the 
hostile environment, cryptography is widely used. Then here comes a basic security problem -- how to set up 
cryptography keys among sensor nodes? i.e., bootstrapping problem. In my talk, I will give some popular solutions to 
this problem.
