| Abstract: |
| The limitation of weakly security network coding against eavesdrop gro
up is paid attention for its applications in Wireless Sensor Networks(WSNs). Ac
cording to the encoding matrix′s principle，a weakly secure network coding model base
d on global encoding kernel encryption is designed through using neural network i
ntegrated with chaos-based encryption technology. By security transmission the
global encoding kernel, secure communication is possible in a environment where
all the channels are eavesdropped in a communication network. Data simulation sh
ows that the model has a little increase in energy consumption and it has
a sharp improvement on protecting weakly security network against eavesdropping
with a small cost on the energy consumption. |
