Abstract: |
The critical problem of key distribution in
wireless sensor networks(WSN) is analysed. Based on systematic characterizatio
n of uptodate typical key management schemes,their advantages and disadvanta
ges are desc
ribed as well as their applicability.Through considering the application backgro
und and the diversification of architectures and functions of WSN,some promisin
g research orientations are presented. |
